Sheri - Hmm. I kind of doubt that ("xr sometimes doesn't stay in the body long enough to get all of the medicine out of the medium that it's in", etc.). It's a diabetes medication and I can't see it being available for it unless it delivered the promised dosage of medication. I really don't think they'd play with peoples' blood sugar like that (or that the FDA would have approved it). And if it was delivering less, I would think that the maximum dosage would be as high (or higher) as regular, but it's not; max dosage is only 2000mg whereas regular is 2550mg. To me, it seems like a more level dose. I'm not having highs and lows like I was having on regular. JMO
I also lost more weight easier on regular. However, I believe most of it was because of all the running to the bathroom I did because of GI effects. :o
I know everyone has their own favorite. I love XR, it's done wonders for me. Maybe not as fast as regular, but not as harshly either.
