I tried looking through here for a possible answer but could not find one. I was recently diagnosed diabetic 3-4 weeks ago , i was immediately put on a tablet called metformin 500g . I started to take this medication with food, but i have noticed that since i have been taking it i just cannot sleep at night, i could go to bed at 12am and still be wide awake at 5am, i had 4 days on the spin like this, so one day i did not take metformin, that night i had a pretty good nights sleep.
The next day i took metformin and im back to not being able to sleep, i was wondering if this is a known side effect ?and if so what can i do , or is just a coincidence ?
any help on this would be appreciated.thanks
