I had the same side effects as you experience...migraine headaches. I no longer use the product.
5-HTP
My reaction to 5-HTP was terrible. Felt like I ingested a poison. Very sick, felt like fainting, headache...
5-HTP
5-HTP for anxiety/depression
After reading some posts on this website, I decided to try 5-HTP for my general depression and social anxiety. After taking it the first time, I really noticed it made me feel kind of happy and giddy, so I was excited, and I also felt less anxious and more able to be what I consider myself. However, about a week taking just 50 mgs twice a day, I noticed I would get headaches. Then after about a week and a half I got a horrible headache, which I think might have been a migraine. It came on suddenly and lasted for about an hour of excruciating pain and nausea, and more mild pain and tension the rest of the day. Afterwards, for about a week, I started getting strange pains all on the left side of my body, in my leg and hip and shoulder. The migraine was on the right side of my head. I was pretty sure the 5 HTP was causing my everyday headaches, and was starting to feel like it lead to the migraine and subsequent left-side-of-the-body pains. I stopped taking 5-HTP and and my head-aches and body-aches have subsided completely. I am glad this supplement has worked for some people, but I just wanted to share my experience.
5-HTP
WARNING!
One time I purchased a bottle of 5-htp, and after taking one capsule morning & evening, just twice, I threw the bottle away. My reaction to 5-htp was horrific; upon further research I learned that high levels of serotonin are associated with SEVERE ANXIETY. I also read that the spice ginger is a serotonin antagonist, so I have a bottle on hand, just in case I ever feel so anxious ever again.
Then I read somewhere online that there is a set of people whose depression responds to Acetyl L-Carnitine, they said the depression lifted in these people when using 3-4 grams a day, and to take two grams of acetylcarnitine on an empty stomach, first thing in the morning.
This amino acid is the most amazing substance; I've never been able to take more than 2 grams per day - there is such great mental clarity, there is utter inability to be depressed, but there simultaneously is no euphoria - just calm lucid clarity. I've read that it assists the brain in making many different neurotransmitters - so it is not anything, not anything at all like 5-htp which floods the brain with serotonin - which, if you don't need it, might create severe anxiety.
