i was told in this forum that each person is beter on a dif dosage of metformin dependin on there body, when i was on the lower dose in jan-june i lost about 10kilos, i hav been on the higher one from june and i hav only lost about 3 in the past 5months, so i sugested to my doc mayb im beter on the lower dose and she said that cant be true cause as im not small in my size i should logicaly be beter on the higher, if any one has any input on this would be much apreciated
