Hi Julia,
I had a lot of the symptoms you have had and more. I was on it for about 3-4 yrs. I have been off now for 4 months. But while on it in the begining it was great, however it slowly crept up on me and turned horrible. I had severse shortness of breath, chest pains, leg cramps, arm, leg and face numbness. Was super dizzy all of the time. I could no longer run which I did 5 days a week, it was an effort to drag myself out of bed to just walk. If you read a lot of the old posts you will find a lot of similar posts to yours. Oh and I also couldn't tolerate anything like pizza or junk food, however I gained about 30 lbs. in 3 months. It was really crazy how it happened especially since I couldn't really keep anything down. I was constantly having to go to the bathroom. I also had what I thought was food poisoning about 6 times, however now I know it was the darn pill.
so if you are not already I would go off of it.
