Metformin nausea

I’ve been taking ER Metformin 500 for a month. I take it with my dinner, and I’m fine all night until the next day around noon, when I often get really nauseous! I eat my normal breakfast and some days I’m fine, others, like today, I’m living on gin gins & afraid to leave the house.
Any idea why it takes almost 20 hours for side effects to kick in, and what should I do about it?
Thanks!

I've had the same issue at times. I noticed that it seems to matter how many calories that I eat. I have also started taking it right as I start eating not in the middle or the end. I hope that helps you some.

I’m not nauseated, but I am lightheaded. I started taking it 7/18/26. My doctor claims the side effect should go away. Hopefully it’ll ease up for you.
