Suggest Remedy For Pain, Diarrhea And Irregular Bowel Movements

I'm 36yeqrs old and have had 3 children. I went from drinking more than a fifth of vodka a day to now drinking less than a liter of wine per day. I have been on adderall for ADHD subtype 1 for more than 3 years. It interferes with my ability to swallow food, however I do eat when I am hungry even if small portions. I take hair and nails vitamins. I know I'm dehydrated. I drink as much water juice and milk that I can stomach. I crave salty things but often cannot physically swallow. I'm a stay a thomas mom who is exhausted all the time. I am losing hair. Not at an alarming rate but my hair used to be thick and now I can see my scalp. My teeth have always been weak. I chipped 2 teeth eating lasagna yesterday. I drink about 8 glasses of water per day and eat as much as I can stomach. I have 1 kidney as I'm a living donor. After I stopped the vodka the petichriae (sorry for the misspelling) went away. I have to see my PCP very soon to get my refill. I'm going to be honest with him. I have always been so. I've been having bowel issues. Pain, diarrhea and constipation. My sister has Crohn's disease. I'm always tired but that may be due to raising children and having no appetite. It's hard even to drink water or Gatorade. I'm calling my dr tomorrow to schedule an appointment. Any tips or advice? I'm so tired. And scared to eat and even wash my hair.
