I've been in Glucophage SR for a few months now and is great but lately I've been weeing like a horse all week, several times day and night. I'm craving sweet food again. I just had a big meal and my bloods were 17.4 then 30mins later 24.1. This is by far the worst I've had. Even after a large meal is never been above 13. Over the last 10 days I've switched from Amitriptiline to Gabapentin for nerve pain caused by 4 bulging cervical discs. Could this be related to my recent blood sugar problem?
