Mark, those where just examples that should show that I am not able to switch off and start to think about unimportant stuff, even though I feel fatigued and exhausted.

Before my injury, I also had this switching off problems when I had a stressfull time. Now it takes 2-3 hours until I fall asleep. I assume that this has to come from high stress levels. I feel how my recovery is blocked by this condition.

I also had this problem when I didn't take a single supplement. Interactions are not the culprit.

I will give 5 htp a try. I also consider to add Pharma GABA and DHEA.

The seriphos seems designed to do excactly what i want, reduce cortisol levels. Some amazon reviews showed that it helped a lot for sleeping. http://www.amazon.com/Interplexus-Se.../dp/B000N23AE8

I am just a bit worried how this stuff works for TBI patients, if it could maybe impede the healing. Looks like I would be the guineapig.
