I have been taking between 5 and 10 mgs of methadone daily. I cannot seem to stop. Every time I try, I get very, very depressed and experience abdominal pain, chills, hot flashes, and sleeplessness. The depression and tremendous anxiety are intolerable and I end up taking more to avoid it. Question: Am I harming my body and/or mind with this stuff? How can I get off without the horrible feelings?

I was just wondering — can drinking sugar-free energy drinks promote weight loss? I remember hearing somewhere a while ago that it is possible for those drinks to cause those sorts of results. I am a busy college student and would love to think that it would be possible to keep my energy level up while shedding a few pounds at the same time!

My friend and I snorted a 10 bag each of heroin. Our heads began to feel heavy after ten minutes. Soon we entered into a dream world in which we hallucinated heavily. We talked to people who did not exist and we were very confused. I could not remember anything about who I was. I only remember certain parts of the four-hour trip that followed but I felt like I was on mushrooms for about two days. We could not read for that amount of time (nothing was in focus). What do you think we took? PCP? Bad synthetic heroin?

Recently I have started snorting Ritalin and Adderall (not at the same time though). I have found that the effects closely resemble that of snorting cocaine, but are not quite as intense. I really like doing this, because it's much cheaper than buying coke. However, I was wondering exactly how dangerous this might be, if even at all, considering it's a prescribed drug and I never snort more than the average dose that you would take orally. If you could tell me what the danger in doing this is and what I might possibly be doing to my body, that would be great.

I'm thinking about trying heroin. However, this prospect makes me nervous because of all the media reports of people becoming so quickly addicted to it, wasting away, and even dying from overdoses. Any advice?

I've heard that drinking coffee and grapefruit juice at around the same time can extend the effects of caffeine. Is this true? I know that grapefruits can increase the bioavailability of some drugs... what about caffeine? Is this at all dangerous?

Is it true that women can apply testosterone cream to their vaginal area to increase sex drive?

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?

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?

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?
