I received the shot the other day. I received one last year as well. I've been having cold symptoms and zero energy at all. I hate that overwhelming feeling. I've been spending a lot of time in bed. However while I realize there is a risk in taking this or any shot I still feel the positives outweight the negatives. Hopefully I will start to feel a little better soon. I know I couldn't handle a full blown case of a severe flu on top of my other conditions including FMS, CFS and lupus amongst others. I still think its responsible for me to have the preventive shot. I'm sure a lot will read and say how they disagree and site horrible things from the shot but I'm sure we all can site horrible things that happened to loved ones, even those without other conditions, from the flu.
