well if your mind is that active there is also another thing that could play a role.
gamma amino butyric acid [GABA] that plays a role i calming and regulating our neural signal firing patern in the brain.
Also ppl that have to low levels of it have fear and hyper etc.

No idea of u still can buy gaba..think these days its only on a docs medication list.
else u could test it, I bought it when it was still legal, u sleep good on it.
so its either that or to low serotonin levels.

mm yeah i look some up, however the med database about 5-htp lol is quite ehm science language.
