... doing 1200 mg of motrin every 4 hrs for 3 weeks, the pain was terrible..My prozac quit working and I am in full blown ocd and depression..My doctor said the motrin can make the prozac stop working when abused, now I've been taking 30 mg of prozac for 2 weeks, hope I can get back to where I was before the accident, this has been a roller coaster ride, will the 30 mg help me or should I stay on 20 since it work so good..I haven't had no motrin in 2 weeks
