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?

A couple of questions for you: what are the long-term side effects of one abusing prescription painkillers, such as Vicodin? What advice can you give to someone who has gotten off of them to help them stay off???

What is "gaming addiction"? Is it a real thing? I can play some games, like World of Warcraft or League of Legends, for a whole day, and I've sunk 150+ hours into RPGs. How many hours in front of a screen are too many?

I have been shooting cocaine steadily for almost two months now and want to know what the difference between the physical and emotional addiction is. I am not sure if I have been experiencing withdrawals, but I feel sick a lot lately. I know shooting heroin has made me sick before. Can cocaine eventually make you dope sick as well?

I just started taking Zoloft today. I am going on vacation next week and am wondering if it is safe to drink while on this medication. I can't seem to get a straight answer from anyone. I'm not talking about drinking to oblivion; I'm talking about having a couple of drinks by the campfire. Is this okay?

I, like many Americans, take Zoloft, 50mg a day.

My question is: Will this show up or alter in any way a pre-employment drug test for future jobs? Should I even mention that I am taking it to the screener?
