Why do I crave sweet things?

I try to eat a piece of fruit for dessert after a meal; however, when I have substituted after-meal sweet cravings with fruit, I still end up craving some other type of sweets (i.e., candy, chocolate, ice cream.) It seems that after every meal, I can't feel satisfied until I have eaten something of this food category. I do try to listen to my body and this appears to be programmed into my mind telling my body it is wanting this food consistently. Can you provide any explanation as I am trying to lose weight and this type of food is empty calories and unhealthy? I work out six days a week and have recently given up smoking.


Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


How long should I wait to use Viagra after using poppers?

I know that it is extremely dangerous to mix viagra (or other ED drugs) and poppers (amyl nitrate), and that one should wait for 24 hours after using viagra (to let it get out of your system) before using poppers. My question is what is the waiting period after using poppers before it is safe to use viagra? In other words, how long before the physiological effects of poppers wear off?


What are the health effects of recreational codeine use?

I like to use codeine occaisionally (once or twice a week at most) to help me relax and feel a minor high. Typically, I'll take about 90 to 150mg per session (100 to 200mg per week on average). Sometimes I take Tylenol-3's, and sometimes I extract the codeine from these pills and drink it pure. What are the potential health side-effects of this usage, both short- and long-term?

Thanks!
