Hi Stevie
Thats very interesting, I'm on that level of medication 6 x 500mg Metrormin,8mg Rosglitazone and now 8mg Gliclazide as well until my referall to Diabetic Specialist comes through.My BS is high,HBa1c currently 11.9.It doesn't work(for me)!!
Will be bringing up Byetta/Sitagliptin at the first opportunity as well as asking for a GTT and c-peptide test.
Sounds like Sitagliptin is the one thats doing it for you, well done.
Regards Pete
