Hello all, I've been reading a lot of good information about diabetes on this forum so I decided to register. I have just been diagnosed with type 2 diabetes (about a month ago). My doctor put me on metaformin twice a day but it did very little for me. My sugar was in the high 200s every time I checked. I went back and the doc added glipizide. I took it for the first time this morning. When I checked before lunch, my sugar was 90. It has not been this low in a while. I'm pleased but concerned about going too low. Any advice about when to test or side effects with these drugs?
