Regarding the bathroom issues, we cant offer medical advice, only personal experience.
When I drank, I would sometimes have to go so bad I could barely hold it. I had some close calls. Stopping helped.
A short testimony...
I drank a ton off booze off and on for decades.
Only a Dr. could have decided if I needed medical detox.
I made it through, mentally scared with horrid anxiety and feelings of dread and doom.
I still get those feelings but now clean for this long, I am used to it being way worse. So, i got better. Not perfect, just better.
I sort of tapered down. It went pretty quick. My last binge was about half a bottle of whisky in 12 hours.
The av told me anything to keep me drinking. It is still around.
Old craves become new again. I must embrace and cherish my sobriety vs fight my addiction. Fighting gets exhausting.
Embracing and loving being super clean is forever uplifting.
Thanks.
