ibromyalgia
"Miracle drug! The side effects can be daunting at first, like tingling/numbness in extremities that won't stop for hours, but if you increase your water intake substantially and power through, it's totally worth it. 

My daily tension headaches are 90% gone, which is huge for me. It didn't do much in terms of overall muscle pain reduction or the daily body aches, but I did lose over 30 pounds in four months. I stopped drinking all carbonated drinks (because it makes them all taste super flat weirdly) and definitely am not as hungry as I used to be, so that's just a bonus."
