Well I just talked to the nurse and I told her that so far I feel good. So I said to her that the other nurse said that side effects usually happen within 2 to 48 hours after the injection does that mean I am in the clear if I dont get any after 48 hours? She laughed at me and said NO. That these side effects can happen at any time...usually after your body figures out that there is too much anti viral drugs in my body. She said my body makes this stuff on it's own. Damn I thought I was in the clear...you know on the 48 hour count down. She said that everybody is different. Some feel it almost right away others it takes a little more time, and some are lucky and breeze through the treatment. I am learning that there is no way I can make plans while on this medication. I guess I am just going to have to play it by ear.
