I ended up in the ER last Saturday because I felt so dizzy. The Doctor in the ER said he felt I had vertigo and that is was probably unrelated to the Metformin. I didn't feel like the room was spinning, rather I felt drunk. I felt uncoordinated, wobbly, like my balance was off and a bit lightheaded.
I am wondering if any others have experienced this type of side effect? If so, did it go away once you'd been taking it for a while?
