There are a couple that I use occasionally that work for me. I usually take them when I'm feeling a little stressed out or anxious and don't want to resort to taking a prescription benzo. One is a homeopathic remedy "Bach Rescue Remedy" for occasional stress or anxiety. Another is a sleep aid "Hyland's Calms Forte". It is 100% all natural and non-habit forming, non-drowsy formula. You can use it as a calming aid also at 1/2 dose. You can find both for cheap and read all the customer reviews and experiences with the products at www.swansonvitamins.com
Hope one of these works for you.
