I've used a little CBD in the past, but with little to no regularity. I have a rather high tolerance for most things, so after reading here and there, I decided to go with the 1000MG Oil. I'll be honest, as much as I do believe it has given me relief, I also sometimes cannot tell, I have simply been so exhausted lately and running on so little fumes that I don't know if it's the CBD or if it's me, me being just burnt out. HOWEVER, my girlfriend has started taking half a dose .5 ml of the dropper prior to going to bed and says she not only feels relaxed, but has been getting to sleep, sleeping, and waking up in a much better way than before, with no grogginess or bad side affects. We do believe we will be purchasing more again soon, perhaps a different brand or dose.
