Rick Morris is one of seven CNN viewers participating in the CNN Fit Nation Triathlon Challenge. He quit smoking on an episode of "Sanjay Gupta, M.D." and has been smoke-free since.

About two months ago, I quit smoking. At the time there were many reasons influencing my decision to finally choose a smoke-free lifestyle. I was worried about my health. I had high blood pressure. My doctor and everyone I knew was encouraging me to kick the habit. My family history is one of lung cancer and diabetes. The list goes on and on.

Now that I've been without tobacco for the past couple months (63 days, to be exact), I've noticed some changes in the way I'm living.

All are positive and are in direct relation to my body's depletion of those nasty chemicals I've called friends for the last 12 years.

So I thought I would list those changes and explain how I have been affected by each. Though my list is restricted to 10, it is by no means an exhaustive one.

1. No more chronic cough: All smokers know what "smoker's cough" is. I didn't realize how annoying this was until I stopped coughing all the time. After about a week being smoke-free, I noticed I didn't have to clear my throat every few minutes.

I recall plenty of times when I was at a function or meeting and needed to cough so badly, but couldn't because I knew it would be rude and interrupting to those around me. It's like an insect hovering in your throat – not touching, just drying everything between your tongue and your stomach – and you can't do a darn thing about it.

2. The smell: I didn't know I smelled so badly until I was around other smokers. Their clothes, home, car, even their pets reek!

About a week after I smoked my last cancer stick, my daughter and her boyfriend, a smoker, dropped by for a visit. Their dog always peels for the door and makes it into the house first. Yeah, I actually smelled the odor of cigarettes coming from the dog.

3. No more cleaning butts: I swear that cigarette butts would multiply when I wasn't looking. I once placed a butt can out back on the patio and initially used it as intended. Pretty soon, I was too lazy to walk down the steps to the can and just started flipping cigarette butts out into the yard, in the area of the butt can (as if I were shooting a jump shot). I rarely scored.

Eventually, they were lying everywhere. So much that I would just wait until the weekends to "clean" them with the leaf blower. Nasty, nasty, nasty!

4. It's just an extra $200 per month: Really, the extra money wasn't even noticed, as I can easily spend that on a night grilling on the patio (I love king crab and filet mignon, and only the finest Belgium beer!) So I really didn't look at this as a true benefit of not smoking.

But, with the price of cigarettes reaching about $6 a pack in my area – and up to $11 in other areas of the nation – I discovered this adds up. And, it was clear the price of tobacco was just going to continue to rise.

So, I got out my calculator. $6 a day multiplied by 365 days in the year. Comes out to $2,190. Looking at this long term, that's about $122,000 over the next 56 years (when I turn 100). Assuming cigarettes continue to increase in price at the present rate, then it's easy to see that number growing to half-million dollars. Invested wisely, I'm sure I can leave someone a big, fat payday!

5. Lost productivity: Sure, we all need a break or two during the work day. But I realized I was taking about 20 of these 5-minute breaks. In all honesty, each was probably about 10 minutes. About two-thirds of my breaks were when I was at work (I have a home-based web development business). So, that's more than 2 hours of breaking as opposed to working.

How in the world was I getting my work done? I have since realized that I wasn't.

6. Food tastes much better: I don't know if it has something to do with a cleaner mouth, but food simply tastes better. I also find that I use less salt.

I've heard on several occasions that if one quits smoking one gains weight, but I would warn people from using the weight-gain excuse as a viable argument when attempting to become smoke-free. Trading one bad habit for another isn't the way to go.

7. Non-smoking or non-smoking?: I think the air-line industry coined the phrase: "Smoking, or non-smoking?" And, I think it was the first group to eliminate cigarette smoking from a certain area (the airplane).

Today, it's almost preposterous to think we once smoked during an international flight on a 747! "Non-smoking or non-smoking?" seems to be the rhetorical, unasked question wherever you go these days. It's understood. There will be no smoking here, or here, or there, or over there, or in there, or... well, you get the point.

Unlike the Golden era of the 1920s and 1930s, when smoking was an upper-class hobby, a smoker's world is an unfriendly one today.Since the airlines quit asking that redundant question, smoking has been eliminated from virtually all public places. Restaurants, high-school football games, town parks, even bars and drinking establishments have become smoke-free.

For smokers, drinking a beer without a cigarette is like playing pool without a beer! Whether smokers realize it or not, the very fact that one uses tobacco limits them in myriad ways – especially socially. I don't have to worry about that anymore.

8. Dry, sticky contact lenses: As a wearer of these miracle discs of ocular health, I know what smoking does to your contact lenses. Smoke makes them dry. They become cloudy and you're constantly rubbing your eyes. Eventually, your lenses get to the point where you must get them out.

Fortunately, I wear disposable contact lenses. All I had to do was pop in a new set. But, at a couple dollars per lens, this was costing me. How to solve this annoying problem? Quit smoking!

9. Physical appearance: In the few months I've not smoked, I can tell my overall physical appearance has improved.

My skin isn't dry and wrinkly. My bit of gray hair is actually going brown. My self-confidence in speaking directly to someone isn't hindered by my desire to turn at an angle because of smoker's breath.

10. Bye, bye yellow teeth: No matter how hard I brushed or swished fluoride, I couldn't seem to keep perfectly white teeth.

"It's because you smoke," my dentist proclaimed. "And, unless you do something about that, your dental health will continue to deteriorate, thus affecting your overall health."

Bad teeth can lead to serious health effects throughout your body. Yesterday I had a cleaning at the dentist, and plan to keep my teeth white and healthy from now on.
