The one pill I absolutely can't seem to live without is Zyrtec. If I forget to take it, I break out in hives the next day.
My doctor had me on Vitamin D for awhile because my level was low. She took me off of it when my values reached the high end of normal. Now my cholesterol is up, and I just read a story in the news that high cholesterol has been linked to taking Vitamin D pills.
You just can't win. We are mortal and something is going to kill us.
