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?


Do I have bulimia and will it interfere with my birth control pills?

Once a day, after meals — whenever my roommate isn't around, I stick my fingers down my throat and throw up most of the food that I had just eaten. I do not binge — I only purge. I understand from my Psychology professor that the diagnosis of bulimia nervosa requires that the person binge and then purge. I am curious, then, what I have — do I have a form of anorexia nervosa or what? Also, I am on birth control pills and I am afraid that I might hurt their effect by throwing up. How long does it take for the pill to get absorbed into my system? I usually don't throw up until about 5 or six hours after I have taken the pill. Will this hurt the effect of the pill?


Where can I find basic information about emergency contraception?

1) My girlfriend and I had sex twice one night — the second time, we had to change condoms because she was dry and the lubricant had run out. Before I put the second condom on, she asked me to "put it in" without it on for a few seconds; which I did — not entirely all the way though. I instantly realized the mistake and withdrew. Naturally, as I expect, there is a small chance this could have gotten her pregnant. However, this was four days after her period ended, and the condoms we were using had nonoxynol-9 on the inside and outside. I had not ejaculated yet, as a matter of fact, I never did... and I had wiped the tip of my penis prior to doing this to avoid any pre-cum. My question is this: I'm hoping I'm right in assuming the chance of pregnancy is minimal — however, we are considering emergency contraception. What could you suggest?

2) My boyfriend and I had sex last night and we saw that the condom had broke. We don't know when it happened and I've been looking all over for the 72 hour correction thing that the commercials say — just in case. Can you help me?


What’s up with the acid in my throat?

1) I have had acid coming up my throat from my stomach for the last 3 weeks. It comes up and just burns my throat. What is it? Do I have an ulcer? By the way, I get 3 hours of sleep a night, and my roommate doesn't help the situation.

2) I have recently asked you about my would be ulcer. I shall pose the question again. Lately I have this damn acid coming up my throat. I've been under a lot of stress and have strange sleeping habits. I am also drinking a lot of coffee. I drink about 5 cups of coffee a day and my roommate isn't exactly stress relieving. I go to bed about 3:30am and wake up about 5:45am for crew. Am I dying? Do I have an ulcer? What's wrong with me?
