I used to be a heavy smoker myself, but I've quit for 3 weeks now. (B/c I'll be having to take a drug test in a few months.) The first week was tough, mainly because my mind was so clouded I was adapting to trying to think normally again, probably like you're saying you're confused. After that, it got smoother and now I feel fine, just a little depressed but I think it's because I am just not used to doing things not high and I've been pretty bored lately. Good luck you to you and I hope you can make it a month!!
