I recently took Buspar for anxiety I was going through (family illness sparked it). It is a twice a day everyday med that has no side effects if you wean off. I only took it for 2 weeks and was back to normal. I had major issues with anti-depressants years ago and am VERY scared of taking things, but I am really glad I took this. Xanax makes me sleepy too. I was prescribed Klonapin instead, but never took it. It apparently doesn't make you as sleepy.
