I couldn't wait on an IOP because I am sick now. I am not brave enough to use IOP anyway, I suppose I am a coward. I work 12 to 14 hours a day 5 days a week. I do not have the time to sit in a doctors office all day to wait for him to tell me what I already know. Plus pay an office visit. If I didn't get this stuff every year I would go to a doctor to find out what was wrong. Since I already know I can get my medcine over night start taking them and not even miss a beat in my routine. Plus I have 90 so it is enough for 3 rounds if this comes up again. I thought I got a pretty good deal.
