Are u asking if medication has helped people ? Well if ppl tell u that a med has worked for them...it isn't necessarily true that it will work for you. So this isn't quite an exact method to find a med that works. Trying them is the best idea.
If u ask me, I've tried almost all meds from all classes: benzo's, SSRI, and now I'm gonna try IMAO. I also tried some antidepressants, herbal, and some other classes of meds (gabapentinum for example) that are not exactly for SP and anxiety, but they sometimes work. I have spend the last 6 years doing this. Nothing worked. But yet, I belive I wasnt lucky enough to find a med that works for me. Other ppl did.
Only med that worked against anxiety 4 me was zolpidem tarthrate (this is the active substance), witch gave me anxiety free moments, but also lots side effects: lack of balance, freakin' amnesia afterwards, dizzzines, and sleepiness. It has helped me go to college for an year, than the effects wore off, so bye bye college
Also, Seroquel is awesome for my sleep, I take like 100mg to fell asleep, also my mother uses it. I think it could even put a horse to sleep lol
Good luck in your search for the right med FOR YOU, i hope you find it

and find it quick. And remember, luck is not the only factor here, patience is too.
