I'm online now. Hi, I started biting inside of my cheeks about 8yrs ago after having a baby, do you think its a result of medication they gave me?

Unlikely. Your habit may have been precipitated by the events around a pregnancy, but it is not likely to be due to any medication. However, medication can address such obsessive compulsive behavior. Eight years is a long time to put up with it. Please see your doctor or a psychiatrist for treatment.
