Yeah, I am surprised too. I have been so frustrated by this sudden weight gain. I know I am on several drugs that can cause this but I have been on them or similar drugs in the past without gaining weight. I finally started an internet search with lists of common drugs that cause this problem. I went to only reliable medical based sites. Each one listed Benadryl.
Again for me it probably is a combo of things but my appetite and weight are improving off the antihistamine plus I have more energy.
Taper going fine. Dropped a 1/4 tsp today. I am in no rush...slow and steady. My pain has been tolerable.
Love to you all.
