Very disappointed

Have used The Vitamin Shoppe's L-Tryptophan caps and had great sleep. Was buying a bunch of stuff on iherb so thought I'd try the Source Naturals caps because it was cheap - big mistake. Last night had a horrible groggy insomnia and depressed feeling. Will not touch this product again.

Only tried a few times. Makes me constipated. I noticed there is iron in it. Will try another brand.

I thought it will help me with my depression but instead made me more agitated, and gave me bad heart palpitations. Even started slowly, half dosage for two days, then increased to 500mg for the next few days then increased to two at night after a week. Had to stop after 11 days as I felt that I was getting worse. And I even ordered an extra bottle thinking that it will work and i better have a good supply. FEEL SO DISAPPOINTED!

Well I really believed this to be what I needed for a good nights sleep- but it didn't work. I can't believe it!
