I've used everything posted online and from doctors for scabies. The only thing that has worked for me is Dr. Clark Hulda Zapper. After the first day I was able to sleep through the night. I zap twice a day one in the morning and before bed. I put it under my armpits for 10min then off for 20min, then in my socks under my feet for 10 min then off 20 min then hold it in your hand for 10 minutes. Drink plenty of water you will get dehydrated.
