Allergic reaction post WLS???

Just as I suspected, I'm the one in a million who now has low tolerancy for subtle chemical interaction in the body (now post WLS). I can take the iron, but only by itself. Been good since then. But I still cringe when I see shellfish!! It's all in my head though. One day I'll be brave enough to try it again! This suks, cuz I love shrimp!! Thank you so much for all of you who cared enough to write and "talk" to me when I was soooo scared and desperate... Flavia
