bbro-
I was on 500mg also for quite a few years. I recently have been having irregular periods and now this month its very late. My Dr. told me to up it to 1500mg. I have an appt. later this week. my weight, diet and activity levels have been steady and nothing has changed so I do not know why the sudden problems are happening. I do not know if there is such a thing as met resistance. I guess we'll see if it helps. I posted a message on this site yesterday posing the very same question. Has this happened to anyone else??? |
