Advice needed: How do you stop yourself from scratching at night when you have eczema (or any other similar extremely itchy skin ailment)

Here’s the short of it: I have a pretty bad case of eczema concentrated on my hands. It’s been there for years now and I’ve always hated it. Most of the times I can control myself when I’m wide awake (I always have those moments of weakness) but when I sleep I tend to go all Rambo on my own hands. And trust me, it isn’t nice to wake up to fingers with cuts and blood and pain.

I’ve been to see doctors for a long time already. They almost always gave me steroid creams but they never really worked. I now just use moisturising cream whenever the skin gets really dry and cracked.

Still, this doesn’t really help at night when I go all half-asleep and just respond to the itch in the most natural way: scratching. And once I start, it’s so hard to stop and I’ll almost always end up continuing even if I scratch myself wide awake.

I hate my eczema (as does my family) and would love to have normal hands (when I used to play the piano on a much more regular basis years ago, there were times I’d even end up bleeding on the keyboard). It’s even spread to other parts of my hands which were previously normal now and I always feel like hiding my hands whenever people look at them.

Do you guys know of a way to stop oneself from itching? Or if that’s not possible, to stop oneself from scratching, even when one is sleeping and half-conscious at best? Or is self-discipline the only answer (which will slightly depress me as I admittedly find it quite hard to discipline myself)?

P.S.
I’ve gone so far as to agree to tying my own hands into gloves up at night but nowadays it doesn’t work as I’ll just end up pulling them out of the gloves.
