Took my Boniva pill on a Saturday morning, like it said, empty stomach big glass of water, by 10pm that night, I was doubled over, cramping, wanted to puke but couldn't, I would have sworn I had the flu but no fever etc. The next week, I could hardly walk, I hurt every place, my chest and upper back were really bad, if I didn't know better I would have sworn I pulled a muscle or was having a heart attack, I had very bad jaw pain....it took several weeks to feel better, I felt like a grandma and I am only 45 y/o, with osteopenia, and a history of stress fractures...I would rather have my skin peeled off then ever take this again! I am eating yogurt like crazy and munching on tums. I found another website with HUNDREDS of complaints, of the drug along with complaints of all the others like this...I do not understand how they even still have this on the market....honest to god I want to sue....trying to find a class action suit...not for money..I just want this off the market!!!!
