First time I did not feel well was last Thursday. Then Friday I was OK again. It came back Sat. afternoon and I was in bed till Sunday, was OK by Sunday night. Felt good all day Monday and BAM it came back Tuesday. Here I am wide awake at 3am and feeling awful like I am going to throw up. Sometimes I have aches and pains and fatigue, sometimes I have been stuck in the bathroom for an hour. It is the darndest thing the way I am OK between episodes. Was starting to think I had something seriously wrong when a friend called and told me she was going through something similar.
