Anyone take ashwagandha?

I've been taking 1340mg/day for a couple of months now, mainly to see if I have an increase in test, but also for the calming/anti-anxiety.

The main issue I am having is the crazy vivid dreams it gives me and I only sleep about half the night now. I am going to stop taking it because I don't think the benefits outweigh the lack of sleep.

I do think it improved my general mood however but maybe it was a placebo effect.

Anyone have experience with ashwagandha?
