Methocarbamol
"Started taking this for severe back pain and muscle spasms.  I really wish the doctor would have warned me about it!  I started getting sick a couple days after starting it but didn't think about it being a reaction to the drug!  I was nauseated first,  then the chest pressure started, headache, my vision was blurry,  and I couldn't walk across the floor without being out of breath. It was two weeks of pure hell before I thought about the new medicine!  When we looked it up I had more than 13 of the many serious side effects!   I even had to make a trip to urgent care because of it, they diagnosed me with bronchitis!  I  just can't believe they allow something like this on the market!  How long will it  take to stop being miserable?"
