I know we are all different, but my experience with CBD oil, (£70 a go) was a big let down, I tried it for around 5 months but felt absolutely nothing.
Even the herbalist that I was buying it from told me after the third purchase to “stop wasting your money” and try the real thing (Cannabis), but I thought I would persevere.
After the CBD oil I went onto try Sativex, again not a very positive outcome.
Have you enquired about Sativex ?
Even though it did nothing for me, it might help you ?
But like I say, we are all so different, so good luck.
