I've been using a 1000 mg concentrated isolate in 50/50 PG/VG which I then dilute out to 330 mg with no flavoring.
I was using a WPC (whole plant cannabinoid) oil orally but I found it took too long to take effect and was prohibitively expensive. I switched to a vapable isolate as it it MUCH faster acting AND much cheaper.
I suffer from chronic back pain and insomnia, CBD is a great medication for both these conditions.
My daughter suffers from insomnia and CFS ME, I treat her symptoms with CBD now too with some success.
@sonicbomb - I'm not clear on just what quantities, etc. you are using. I'd have to guess, I guess to know how much PG/VG liquid the 1000 mg went into. I.e., how many milligrams per milliter was your mix and how much do you consume per day or per session?
Could you also define 'vapable isolate?'
I'm pleased to know it works for you!
