Like "I am not very comfortable with metformin...I'm currently on 2,550 mg daily (850 mg. X 3 per day), at first, during the first three days, the general feeling was very uncomfortable and a bit scary...I felt very different overall...lost my appetite, head ache, and nauseated...then, I decided to quit for 6 months...during my last vist, my doctor told me that he was going to put me on insulin...I told him that I was not ready for insulin...so, he decided to increase from 500 mg. X 3 daily, to what I am taking nowadays...it's been about a month now, and I'm feeling more comfortable with it than before...as far as my hemo-count, last doctor visit was 11.5...3 points increase from 6 months ago...my sugar count also increased from 130 pts. to 300 pts...that's why I now decided to stick it out to see if there will be a decrease during my next check-up in three months...I'm very much new with metformin...sorry I don't have much to share about it...perhaps in three months, I'll be able to have a better idea on how it works with me..."
