Linchpin, I hope you are feeling better.
For muscle cramps, Flexaril 10mg should help (talk to your doctor or street pharmacist). Make sure you are getting plenty of potassium.
As cliche as this sounds, yoga can do a world of good. Get some videos and do it at home. I recommend "AM and PM yoga", by Guiam (comes in white packaging). These videos are short, only about 25 minutes each. Do it when you wake up, and before you go to sleep.
It is very important to eat a healthy diet. Organic fruits and veggies, ect... I promise you will feel lots better if you stick to a healthy diet (no fast food!)
Good luck.
