try hot tea before bed, and nothing stimulating (tv, computer, phone). we are so hypersensitive as GAD sufferers.
a book you might want to look into is "help and hope for your nerves" by claire weekes. you can only find used copies on the net, and it's really old, but she really is fantastic. i felt like she wrote the book for me. some of the terminology is old (i think she calls anxiety nervous disorder or something), yet she offers some great tips.
as far as the buspar...i've heard it takes from 4-6 weeks to actually start working. a friend of mine takes in conjunction with zoloft for his depression and anxiety/panic attacks, and it works well for him. it appears, from what i've read and heard, that it seems to work better when used with another medication to boost its effectiveness. i tried it and it did nothing for me, but your mileage may vary on it. everyone's body chemistry is different. and don't be afraid to tell your doctor it's not working. if you're miserable, tell him.
i will say this about CBT- it'svery eye-opening. it forces you to find the reasons behind your panic attacks, makes you stay with thoughts that are scary so that you desensitize yourself to them, and teaches you ways to cope through them.
i read that you cried in the bathroom after an attack. were you just shaken up, or do you think there may be some underlying depression there that isn't getting addressed? i only ask because that's sort of what happened to me.
best of luck to you- please keep us posted. and whatever you do STAY OFF OF GOOGLE!!!!
