Itching!!!!

I was wondering if any of you who have mets to liver and terrible itching, have come up with any relief for it?  Can not sleep at night, sometimes wake clawing myself, ouch.

I am using Benadryl at night, lotions, creams, cool showers, sometimes Lidocaine/Prilocaine cream 2.5/2.5% or 4% Lidocaine (works the best but not for a whole night.)  This is just about the worst part of this damn disease so far.

Any info would be GREATLY appreciated.

Thank you so much, Di
