There once was this car. It wasn't working well, so it went very slowly. Then it came upon a hill. And, just as you would think, it got even slower. Then it got over the hill, and got faster again, but still as slow as was before. Great story.
It seems obvious to me that med interactions would slow down the prescription writer. But, I think many of us are having issues whether we have interactions on or not. In fact, interactions doesn't slow mine down at all.
