To the original poster, you've made it this long DON'T get back on the cigarettes, nothing is worse for you health. I've had too many health care pros tell me I'd be better off eating McDonalds every day than smoking (luckily I've never had the habit). My mom died young from the effects of smoking, and I've had several patients who now talk through a device from their habit. As far as sleep aids it really depends on the person and even budget. Melatonin is cheap and works well but gives me an occasional headache. ZMA is something that seems to make sleep deeper and waking up is easier than using Melatonin, which leaves me slightly groggy. Somnidren GH is a nice product, sleep is also deeper and seems to help slightly with recovery. HGH UP is very similar to Somnidren (only in pill form) and taken 5 caps before bed will produce some high quality sleep and incredible dreams. However, if cutting it makes me very hungry. For bulking I'd say it's a winner for sure. With these products only melatonin actually makes me sleepy, the rest just enhance the effects of sleep. Possibly using some of the good info people have provided and using a going to sleep aid (melatonin or doxylamine) along with a sleep enhancer (Somnidren GH, ZMA or HGHUP) might be something to try. I always worry about the drowsy or groggy feeling in the morning so I never taken these together but may in the future. Good luck.
