do you get sick often?

[soundtest]

i don't do serious drugs at all anymore. the last time i touched anything like that was new year's eve, and it was far from what i would consider binging. up until a few months ago i was drinking rather heavily, but i've even reduced that to almost nothing because now i get hangovers (which i NEVER used to get), and this whole "wake up with a headache feeling like garbage" thing changes my whole perspective on drinking because now it doesn't seem worth it. in addition, i've cut back on smoking significantly. i'm not gonna jinx it and say i quit, but i haven't had a cigarette in 4 days now and have no desire for one. perhaps the nicotine withdrawl is a factor? i smoke one to two marijuana cigarettes a night with a cup of green tea to help relieve my insomnia, but other than that i take no medication or drugs (other than caffeine - 1 to 2 cups of coffee a day at work, none on my days off, little to no soft-drinks).

i will try the water and supplement suggestion McClain - thank you. any particular supplement you would recommend (not necessarily name brand, but contents)? i know nothing about this sort of thing.
