OP: Here are some otc "calming" supplements..

Inositol
L Theanine

Meditation work and it's so FREE free free...all it takes is a will to do it. I've been working with meditation since the 70's when TM was first introduced in the U.S. It's amazing stuff and it's very very sad so many suffer needlessly ... One can do a Silent Meditation and that takes no thinking or anything, just get silent maybe a couple times a day 15 minutes or so each.....

To just start taking drugs is not the answer.
