i have been on metformin for a couple of years but gp has just put me on the second tablet, at night and since then i have found it really difficult to wake up in the morning. or i wake up at 8 and next thing i know its 10
don;t know if it is where my body is getting used to the second tablet maybe?
I am still only on one tablet but my thoughts (no expertise) is to try dropping the second tablet for a short time and see if the symptoms subside- it may be completely unrelated. Have you changed your diet at all?
If you have any doubts or concerns always go back to your doctor- it may be something completely unrelated and best get it checked.
