My second shot is in a couple of weeks, only a really sore arm from the first. Never found anything I'm allergic to until the doc switched one of my once weekly insulin prescriptions. Take this on Saturday morning so filled the script and on Saturday I took it, within a few hours I was deathly sick, swapping ends in the commode for 5 days and was certain a truck had run over me. I guess I'm not the brightest bulb on the tree because the following Saturday I thought maybe it wasn't the injection, maybe coincidence that I came down with something at the same time so I took it again. Down for the count for 5 more days. Now looking forward to the second china flu shot. Well, maybe not so much.
