OK, so I switched to metformin ER about 3 days ago. Before that my fasting and post meal numbers were looking fantastic. FBG was in the low 100s almost to the point of dropping into the 90s.
The DAY AFTER I switched to 1000mg metformin ER my FBG JUMPED up to 115, then the next day 112 and today 111. This stuff does not seem to work as well as the regular metformin.
Also, since I started metformin my libido is now completely gone. ED is back with a vengeance too. I think since increasing the dose to 1000mg that my T may have even dropped further from the last test. I will confirm in a few weeks (this testing is getting expensive!!)

So if it is, The only thing that has changed is I am taking metformin now. Do I increase my T to compensate or do I stop the metformin. Ugh. I never thought this whole process would be this difficult.
