Hi Terry,

My husband Jonathan Glass MAC Lic.Ac is the expert, but he brings me CBD oils to try. I can't tolerate ANY THC, so I only use pure CBD. I started with 300 mg. and felt nothing. Then 400 mg was pretty good. Calming.  But now I jumped to 1000 mg. and like it best.   I use it primarily at night, but occasionally will do a dose in the day for calming. We usre only high quality brands. Jonathan does all the research as he is an herbalist and has access to the best merchant companies. I havent had much success with over the counter generic stores like big chain health stores.
