Be Very cautious, take it from a medical professional that researches!
If you would have asked me about this product 6 months ago, I would have given it 5 stars. It puts you to sleep like a baby and you will remember your dreams. I loved that part of this supplement. I even requested that my husband get off prozac, as you can't take with most anti depressants. At first, he too slept well and had bountiful energy. After a few months, I noted that he was very angry all the time and he said the same about me. I even purchased a book solely dedicated to 5htp and read a lot but not all of the book. My husband finally went off the 5htp for 2 months, while I increased my dose from night time only, to a morning dose as well. I was furious with the world. I hated. I actually felt hate in my heart. My husband tried it once more last night and this morning. He came home from work early because he was so angry he wanted to tell everyone off and felt that if he did not come home he would explode and say or do something that was not him, then he remembered he had added the 5htp. Needless to say, no more 5htp unless, I just can't fall asleep, knowing that the next day I will be angry

no no no
I tired this 2 days in a row, first night I couldn't sleep and I do sleep well normally, so as I'm a sucker I tried it the next day and couldn't sleep that night either. The third day I didn't take it and I slept 10 1/2 hrs straight through. Judge for yourself but I love my sleep so these are going in the bin.
