I had a feeling like bubbles in my gallbladder with my last cleanse. Could that be the itching sensation you are talking about? I thought it was just tiny stones moving. Also sometimes when tissue is healing it itches. Have you done the parasite cleanse yet? I would do that just to make sure the itching isn't a symptom.
I was very uncomfortable feeling after my second cleanse. Liver and gallbladder felt tight and stools were very light almost yellow for most of the week. Plus the heartburn. I decided that a stone had either moved to a bad spot or gotten stuck and did another cleanse one week later. Wish I had done it the next day. Immediate relief. Feel great now.
As to the antiacids back when I didn't know what those pain attacks were I took them by the handfull to help with the pain. Probably very bad for me but it did stop me from going to the hospital and probably saved me from surgery. I think if you use them often they can deminish the stomachs ability to balance itself. Just my opinion.

Take care,
