What about L-Tryptophan, SAM-e, or St. John's Wort? Those are all recommend supplements to try if 5-HTP doesn't work for you. 5-HTP helps me sleep and seems to boost my moods overall. I've never heard of someone having that kind of response to 5-HTP before, but I wonder if L-Tryptophan would not give you that problem (the two amino acids are similar but I can't remember exactly the difference).
I'm taking 500mg of L-Tyrosine for anxiety in the morning. Some people take more, some people take it more frequently. I tried Ritalin once for focus (diagnosed with Executive Functioning Disorder, somewhat like ADD) and Tyrosine gives me a similar feeling in terms of mental clarity and focus as well. Check out
"Depression-Free: Naturally" and
"The Mood Cure" for more suggestions. I believe
"Primal Body, Primal Mind" also has some supplement suggestions, but I haven't read that one. In "The Mood Cure", she mentions that some people don't find 5-HTP effective and use L-Tryptophan instead. The book is a little outdated, as L-Tryptophan is not difficult to get nowadays. It was once banned.
I've read a bit about DHEA but haven't tried it myself. My sex drive is still iffy most of the time. Lately, when it shows up, it's full force, but my frequency of desire is still much lower than it once was. I am mostly just trying to give it time because it seems to be sorting itself out slowly but surely.
