Interesting...

I can tell you this...when I was on 500mg at first it didn't bother me at all. I was fine for the week I was on it.

Then I increased to 1000mg and I had the WORST side effects ever. Of course, I thought great when I increase to 1500mg its going to be so much worse.

I was wrong. Once I made it up to 1500mg I was fine. I feel normal, etc. DH suggested to me that MAYBE my body needed the bigger dosage and the 1000mg was too small for me.

I don't think body size should have anything to do with it. I think it has to do with your insulin levels. If you aren't terribly IR or maybe your are more sensitive to the dosage, then yes I could see how a lower dose would benefit you more than say someone like me.

Hope it works out for you!
