I do drink this great tea in the evening after dinner...it's called Tekanne? Relaxing tea, has a great honey flavor.
I was the same way with poor sleep for YEARS, i would be lucky if i got 4 hours a night. I think the wild dreams are fairly common and will subside. for years i did not dream at all. the poor brain is getting real rest and may need some time to adjust.
real restful sleep makes all the difference and one of the best perks of sobriety for me.
