Chewy - I just wanted to lend my support as well. I can relate to how you are feeling right now. I am going through a six month treatment for a chronic condition. It is not life threatening, however, I have been trying to find a cure for the past 16 years, I've been to different doctors, treatments etc. This is the last resort, pretty much!
The first weeks were a nightmare, I lost weight ( not a good thing for me ) and had a just an overall ill feeling that I could not shake.
I am not yet out of the woods, I'm still dealing with several side effects, but I feel the dark cloud is finally beginning to dissipate.
To all of you - I really hope things improve soon!
