Are there any "calming" medicines available over the counter?

By calming, I mean something that will calm my nerves. Like, maybe a mild OTC version of Valium or Qualudes or something like that.

The only available OTC sedative like medications are antihistamines. You want ones that are more on the sedating side such as diphenhydramine (Benedryl) as opposed to Claritin. I suggest a 50mg dose. HOWEVER, there is the potential for a paradoxical effect causing you to feel more anxious/revved up but luckily this is uncommon. Also, No driving after taking benedryl until you know its effects on you. Benedryl is the key ingredient in most OTC sleep medicines.
The important thing is to get to the bottom of whatever is the source of your anxiety and take care of it. In addition to medications try the age old "remedies" of excercize, meditation, herbal teas (like "sleepy time tea" available at most markets), a warm bath, talking out your problem with a trusted friend or family member, etc.

If none of the above is helping then a SHORT TERM "solution" is a prescription medication such as xanax and/or a Beta Blocker such as propanolol (these work by helping to block the physical symptoms of anxiety such as rapid heart rate, sweaty palms etc thus blocking the physical inputs that make you "feel" more anxious! Beta blockers are GREAT for test anxiety, public speaking anxiety etc and have actually been shown to improve exam scores in college students).

Good luck!

A 24 ounce can of Miller Lite is relaxing

Not that I would suggest....however, some people get results with St. John's Wort, or even black cohosh(which is great for women suffering from pms or menopause)Check out a natural pharmacy, they could make suggestions.

Why not try the selec tion of teas? Just go to the tea and coffee aisle in your supermarket, there are many to choose from. One of the best is chamomile tea - this is wonderful to soothe your nerves and has a nice, warming, calming affect on the entire body. Also, Tension Tamer is good - very relaxing. And teas are much better than any drug. Myself, I drink chamomile tea and it works for me!!

I heard St. John's Wort can help a bit

Saint John's Wort. Try half of a sleeping pill. Tea. Nothing but a dark room and quiet.
