Well here's my experience, thus far:

I'm a female, an everyday smoker for the last year who smoked at least 5-6 times a day, average. I'm 5' 7', 160lbs average body, but I can stand to lose about 15lbs. I work out occasionally, like 1-2 times a week. I do a lot of cardio when i do (60-90 minutes). I rarely drink water or tea, and I eat pretty good.

I'm on my 30th day of my Dry Spell for the moment. I bought a THC testing kits from ebay and tested myself the 3rd week into my dry spell. I had a faint line indicating negative. I read the directions and it said even if it had a faint line, you would be qualified as passing. I will be testing myself in 2 more week. But's that's a home test, which is different from a lab.

Now I have to agree with Damon32 on this, taking a break from smoking and drinking has it health benefits. So this dry spell isn't bad at all. If anything it's bringing my tolerance back down so I won't have to smoke so much. But it really all depends on your metabolism, drinking habits, smoking habits and your body composure.
