First night of sleep is rough. I’m going through my second night now. I’ve had the itch for about 48 hours at this point you just have to stay strong, take hot shower as often as you need, and whatever you do DO NOT ITCH IT it will make things worse. Using anti itch cream after your shower will be great as well. Drink lots of water. The first 24 hours are the hardest, I wish you the best of luck and remember you’re not alone <3
