LOL. We must have been posting at same time!
I guess so! My Dr. recommended 5-HTP for my DD who was going through a rough spell. It's all natural so that's good. It does seem to help. I went through a bad bout of this about ten years ago. What worked for me was magnesium. I took a calcium, magnesium, and zinc combo and it worked like a charm. I tried the primrose oil and it didn't work for me. Lots of different things can cause these same symptoms, so you might just have to try a few.
