Unfortunately when you quit youll gain 10lbs most likely because your currently smoking a stimulant.
I smoked for a long time. 10lbs is what I gained post quitting.
I still think you should stop as its almost 100% youll die from it eventually if you live that long.
I've smoked a few years, and have been slowly cutting down, my mom gained over 50lbs after she quit, which gives me reservations on quitting until I am at a lower bf%, I have quit opiates (heroin cold turkey), adderall (cold turkey), but smoking seems to be tough one, I need to get nicotine patches when I do decide to quit. When I was in rehab I was prescribed a nicotine inhaler, I may go that route, it worked really good, I actually coughed from it from time to time, dunno why, but it really cut down cravings. I have overcame A LOT in my life, my next goals are 1. put on some solid clean mass over the next 2 1/2 3 months on cycle 2. Start cutting a month month 1/2 after pct, and be ready for the following summer ( I am 5ish months back in the gym after a few year lay off). Hit 3 years clean in August. Go back to school in the fall after not going for years (im 26 ATM) to finish up (probably 3-3 1/2 years worth of classes) to get my Kinesiology degree. Quit smoking summer/fall of 2015. I know it will happen, I have made a lot of poor/impulsive choices in my life, and over the last 2ish years I have finally started making sound "life decisions", and realizing that they won't be accomplished overnight. This was/is hard for me. If anyone wants a good read, read about the correlation between ADD/ADHD and drug use/impulse control. If someone makes a supplement that can help people with impulse control, they would be ridiculously rich. I am sure it would be a major pharma company that would make something like that, but if some supplement "chemist" came up with some product that could help with that, that would gain such wide spread notoriety, because it could potentially help prevent a lot of the major forms of addiction, not to mention it could help people with binge eating/eating poor in general. There would be a HUGE market for something like that, but it sounds like a miracle supplement if it existed, but definitely something cool if it could be created. Especially these days, a lot of people are dying up by me, in fact someone I knew, and was friends/acquaintances with before he did some grimy things to me and some of my friends, was found dead somewhere in NJ yesterday morning, and I am pretty sure he OD'd, if not it was definitely something drug related... Sorry to get off subject/rant, just throwing an idea out there! Your mental health is just as, if not more important than your appearances or physical health to a degree IMO!
