Is it ok to drink alcohol while taking Xanax?

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?

I've recently dropped acid about 5 times a week for oh... about 3 months now. I have grown mentally and spiritually in ways unimaginable. But friends tell me I am in a false reality now; this brings me off my trip although I now only trip mentally (without the drug). In your opinion, has acid hurt me or helped bring my level of consciousness to a higher level? Am I reaching a state of Nirvana or am I simply a burn out? Please answer this question... I haven't the gall to ask anyone else.

The new acid like synthetic club drug "Foxy" has caught the attention of a few of my friends and I am wondering what kind of high it is — compared to LSD — and what kinds of damage it does to the brain?

I'm a college student who is struggling with the decision on when to see a doctor for treatment with my depression symptoms. I believe that I need to get treated for depression, but I'm just as scared about not getting treatment as I am about starting antidepressant drugs in my current lifestyle. As far as I can tell, I'm exhibiting the classic symptoms of depression, and have been for a while — frequent crying fits, days where I lose all motivation, and sometimes, even thoughts of suicide. But I drink frequently, almost every weekend, and use marijuana occasionally, and I am quite unsettled by the possible interactions between antidepressants and these other substances. In my day to day life I do very well — I hold a good GPA, have good relationships and a good social life, function well most of the time, and stay in shape for sports. I don't intend to change my lifestyle significantly to make room for depression treatment. But when do I need to get help? I don't want to force an unnecessary change on myself, but I don't want to put myself in danger from depression, or even worse, from the drug interactions between antidepressants and alcohol or weed. What is the tipping point?
