I have had no major attacks since I learned what they were over a month ago. I've been on Xanax and I tried Lexapro, but it made me sick. I've also been using herbs and vitamins to support my body and female cycle for several months. Since I went off my birth control, I've been getting tingling in my head, neack and arms. I went off all herbs and vitamins yesterday. Unfortunately, I usually take a Vareian combo at bedtime. I couldn't take it, so I took 1/4 Ambien. I slept very little and wound up taking a 1/4 Xanax (.25 mg) at 4am. I am very sensitive to the drugs, so a little goes a long way, even though my doc said I can take up to 2 tabs. The valerian has been working for me for years, but I need to test this tingling thing. Does anyone else have to take Xanax to sleep? I'm thinking about combining it with 1/4-1/2 Ambien (5 mg.), which the doctor told me I can take a whole one if I need it. Is anyone else experiencing sleep troubles? I seem to wake up tired all the time. Am I going to get hooked on this stuff, because I hate the idea of taking drugs if I don't have to, especially if they're addicting.
