I used to take Benadryl to sleep but I do not anymore it used to give me very the dreams period I took it a couple years ago when in a very bad flare and it helped initially but then made it way worse I think. I wonder if there's any connection.. Benadryl blocks the neurotransmitter acetylcholine which whereas mestinon enhances it. I seem to have a rebound adrenergic release or dump after having taken it
