I have to agree with Mariel141. I got hit with GBS a little over a year ago and I still get the burning feet, legs, hands and face 24/7. I can ignore it during the day but the nights were rough. I couldn’t sleep for more than 2 hours at a time and usually couldn’t get back to sleep.
I can’t take NSAIDS or opioids so pain control is a problem.
I tried CBD hemp oil for another issue as an anti-inflammatory about 6 months ago. It didn’t work for that but I found it puts me right to sleep at the end of the day and more importantly I stay asleep all night. I have had insomnia problems for 20+ years so this was a big relief.
The downside for me, I can only take it at night. Even at low dosages I was falling asleep during the day if I took it in the morning. It also makes getting up early in the morning very difficult. I now have a strong tendency to fall back asleep after the alarm clock goes off. It also takes a couple of hours for the cobwebs to clear in the morning. I also can’t take caffeine.
It seems to me that the effects last 10-12 hours regardless of the dose.
I found a product called Hemp Medix to be the best price for the concentration. A $60 bottle lasts me 3 months.

good luck
