I think and I hope it was all because of my recently diagnosed hypothyroidism. Yesterday, my 6th day on the thyroid pills, I felt remarkably better and I didn't even have to pig out either. Today I feel great!!! I had basically given up hope and I felt so horrible, I honestly thought I was going to die. I am just scared that the symtoms will come back so I am hoping it was caused by the low thyroid. Just to let all yous know now I am fine again.
