Well, I've been there and feel your pain. A little more than a year ago I tried Lexapro and it did the same thing to me....I refused to take another pill or another drug that worked anything like it, pharmacologically. Some people just don't tolerate them. Benzodiazepines are an option for you. The side effects are tolerable. They, of course, have a downside but the bottom line is they almost universally work for treating A/P so it's worth discussing the risk/benefit scenario with your doctor.
If the natural stuff doesn't work out, that is.
Another problem with taking something that's unregulated is manufacturing inconsistency. You could go from batch to batch and experience a very wide degree of efficacy with a "natural" product. Brand to brand, there's sure to be a difference. No standards, no testing, no regulation...this stuff is supposed to work on your HEAD. Pretty delicate organ. I know some people say the pharmacos produce a lot of poison, and they do, but there's an awful lot of poison found in nature, too.
Don't want to discourage you. Like I said, some of the products probably do work, and some of the companies out there may have a very tight supply, manufacturing and distribution process which yields consistent substances year in and year out. But do your research and learn all you can before putting anything in your body.
