Never in the past have I had the itch that you're referring to. This time around, I itch everywhere, and it moves around. Skin irritation moves from forearms, chest, palms, bottoms of feet, legs, and between my toes/fingers. It's not bad when I move around or am active, but bad when I'm laying down, sitting, or resting.
I've found that drinking a lot of water helps a bit.
I gave in not sleeping much after a week with a nightcap and it got worse!
My body is definitely telling me something is urgent, and need to listen. I woke up this morning at 3:30am with my chest itching like crazy, and I drank 2 glasses of water, and it went away enough to get a couple hours of sleep.
