I’ve done water fasting before (3-5 days at a time) and I love it. It typically ends because I succumb to temptation. I just started taking phentermine today. Would it be dangerous to do water fasting while on it? I would hate to risk anything but feel like it could help me.
Answer
You need to ask the doctor who prescribed it. One of the major reasons to take it is to supress appetite so you’re typically expected to eat very low calorie. You really need to ask exactly what the doctor wants you to do.
