Hi I Was Wondering I Am Currently Coming Off Laxatives.

Hi I was wondering I am currently coming off laxatives. I have been abusing them for about a year recently up to 8 a day. How long will it take aprox for me to have a BM on my own? For the bloating to go down? I've "gained" 5 pounds is that normal? How much weight gain is normal? Is there anything i can take to help me have a BM thats safe because i already drink a lot, eat fiber and am doing light exercise. I am recovering from an eating disorder on my own.
