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?


Why can't I stay awake in class?

Lately, I've come to realize that I have a very powerful tendency to fall asleep in class. It seems that I can't stay awake in any lecture style class where I have to listen to the professor and take down notes — where there is minimal engagement on my part. I've pretty much fallen asleep in all of my lecture classes, during one part or another for the whole semester. I think I'm getting regular sleep — six hours at a minimum. I don't like to drink coffee or anything.


Can cocaine make you 'dope sick'?

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?


Is it harmful to sleep on my side?

Is sleeping on our left side in any way harmful for the heart (or anything else)? Some people tell me we shouldn't do it and others tell me it's actually better than sleeping on our right side. What's the truth?

Thanks!


Is it okay to drink alcohol while on Zoloft?

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?
