This is a summary of the responses that I received regarding my request for
help to relieve the intense itching associated with DH.   I received 30
responses.  I sincerely thank all of you for your help.

I'll start off with a list of things that the "list" says triggers itching
outbreaks for them.
8 said stress
4 said Iodized salt
4 said shellfish (shrimp / lobster)
2 said I'm not as GF as I think I am; probably consuming hidden glutens
somewhere
1 said caffeine
1 said hot baths bring out a rash
1 said to avoid casein in milk
1 said be careful drinking tea (all are not GF)

The list of helpful suggestion follows:
3 recommend Dapsone
2 said to avoid Dapsone, "nasty" stuff
2 suggested Cortaid Cream (1% Hydrocortisone)
1 suggested Claritin (allergy prescription, also used for itching associated
with hives)
2 use small doses of prednesone
1 suggested Sarna Lotion
1 suggested witch hazel for temporary relief
1 suggested alcohol for temporary relief
1 suggested Benadryl
1 suggested Rhuli Calamine Spray
1 suggested Neutrogena, Norwegian Formula
1 suggested Diprolene Cream
1 suggested Pscorcin
1 suggested Lidex Gel (prescription)
1 suggested Zonalon (prescription)
1 suggested Temovate
1 suggested Triancinolone Cream
1 suggested a homeopathy formula called Apis 39c
1 suggested mud from the Dead Sea
1 suggested doing Yoga for stress relief

Of course, I couldn't try everything, but the ones I'm using are helping.
I happened to have a prescription of "Claritin" for allergies.  So I started
taking those pills in addition to using Cortaid, 1% Hydrocortisone cream,
twice a day.  The Cortaid cream immediately gives me relief and takes the
away the temptation to scratch.  I also used, on one occasion, the "Rhuli
Calamine Spray".  That too is cooling and also gave me relief.  The only
thing a didn't like about the spray is that it dries leaving a pink
application.   Not too attractive.  My condition happens to be on my legs
(knees to ankle).   However, the rash is far from attractive also!

Thanks again for everyone's help.
