I tried it years ago and I tried it recently but the muscles on my head, neck and shoulders feel extremely tense. I had to take a benzo or levomepromazine to get rid of it.
Coincidentally, when I tried l-arginine years ago it also gave me the same tension, but when I try it now I don't have a problem, it actually relaxes me some what.
In the case of l-arginine it seems to do with vasodilation (NO) while with ashwagandha I assume it's about the muscles, since benzos work.
What could be the reason ? Any thoughts ?
