Find a way to read all the comments that refer to the cilantro/chlorella smoothies you can. They work for a lot of people but sadly, not me. I think I got a little benefit from NB UVB light treatments. I use Eucerin Anti Itch for temporary relief like overnight or waking hours. At night I take Hydroxyzine. I found out two days ago I have shingles and that's a new experience. So far, it's a different kind of itch and not as painful as I expected. I started Valtrex a few hours after getting my red spots so maybe that's helping. I didn't get Grover's until a month or two after retiring so I've never had to sit at a desk itching all day.
