What\'s wrong with me?

So I've been on metformin for a month and a half now, and I still don't see that its doing anything beneficial. I don't think I've lost any wieght although I do have to admit I'm a coward when it comes to scales.... The only thing I've noticed is abdominal pain, I have to poop a LOT more now than I ever had before, I get nauseous at the drop of a hat, my sense of smell has increased but that could be because I quit smoking 3 months ago. I get dizzy for no reason... And I'm on an emotional roller coaster from HELL! I feel so sorry for Joe lately. He keeps getting yelled at and this time he didn't do anything. And if I'm not yelling I'm crying. I DON'T CRY!!!!! What's going on with me?!? Oh, and I'm always having to pee lately. And I have a sharp pain in my rib cage. It honestly feels like I've cracked a rib or something. And I know that I haven't. I have a Dr.'s appt on the 25th of this month. I'm going to bring all this stuff up. That's if I can wait that long with the rib thing. I don't know... I may have to go see my GP before then....
