Well, metformin is known to cause some digestive distress initially, some get over it in a couple of weeks, for some it takes a little longer, but not that long. That ain't right it causing you that much trouble that far along in it. There are some people that just can't take it for the very thing you experienced. Your doctors should have had taken heed of your concerns and found something else a lot sooner. If you have issues with your new med, you need to let your doctor know right away. You might want to quit it right then until you can talk to your doctor, but don't just quit and say nothing. I'd almost bet that your wife might blast you if you did that.
