Yes in case your doctor didn't explain it to you, it can take six to eight weeks to feel some positive effects. You may or may not have some unpleasant side effects immediately. These usually subside in a week or so. Report any side effects to your pdoc and hang in with it. If you have supportive people around enlist their help, sometimes they will notice signs of improvement before you do. If they notice positive changes, they should let you know so it can bolster your confidence. Good luck!
