Hello, I've been taking metformin for a month and I think it's making me feel terrible.I feel sick almost every day, feeling sick, dizzy and my stomach is bad too.Does anyone know if this is normal?If so, does it happen at some point?It seems that I am finally controlling my insulin resistance but the truth is that I don't know if it's worth it.

Greetings and thanks.

When do you take it?Before or after eating?

It's very hard on the stomach, what happens to you happens to many people.

I take it on a full stomach.At first I had some diarrhea but it soon went away...

@isabelbota I take it right after I finish eating.What bothers me is that it's not just stomach symptoms, it's fatigue, dizziness, headache, the feeling of being sick all the time.

@"nigiri, I don't know if you have tried changing the injection area, sometimes the resistance is produced by areas of lipodystrophy..

I have read that metformin gives side effects at first and then they go away... let's see..., but what a bad body it leaves..., but what a bad body it leaves...

@nigiri make an appointment with the endo and tell her about it.

I took it on debut and it hurt my stomach, a horrible pain.

If not, stop taking it yourself and see if you improve.

In the end, each one is a world.I was taking metformin for two more years (before starting insulin), and I did not have any additional discomfort or symptoms.

Talk to your endocrinologist to see if berberine, which is a natural product similar to metformin, could work for you.
