I've been taking St Johns Wort and haven't noticed a difference I don't think.. My other choices were 5HTP and Valerian but I thought that Valerian was more of a sleep aid and was scared that it might knock me out! As far as the St John's Wort goes though I'm only using 600mg a day and the recommendation is 900mg so maybe when I start popping another pill maybe I'll feel a difference? i don't know.
Hyland's Calms Forte (do a search on google to see packaging). Its at the health food store. It can be found under natural sleep aids. My mom and I also use it to take away the "nervy" feeling. It is as the title says, calming. It does help with sleep too! My husband and I use it on those nights where our minds go a mile a minute and can't get to sleep. Its non-habit forming and gentle homeopathic remedy.
