I can relate to the itchiness part! I'm so sorry. What do you use when you use the bathroom? I've found wipes versus just toilet paper and barrier cream to be really important.
Ask your doctor about a prescription for Cholestyramine! It really saved my quality of life. It essentially neutralizes the stomach acid that is a major culprit of the itching. I really couldn't function normally for how frequent/intense the itching was and this has almost eliminated it. I don't like the idea of being on medications long term if I can help it, and I hope that as I heal from takedown my body will properly break down bile on its own. But until then, this is a HUGE help to me. They started me with half a packet, twice a day, and I've already been able to go down to once a day after just a few weeks of taking it.
My nurse told me it's safe to lower, stop, and restart taking it on my own so that as I heal I can do what works best for me. I hope this info helps! Feel free to message me if you have any questions about it!
