Sorry you had such a horrible side effect Butterflies. Only side effect I had from it was I couldn't sleep, but the doc gave me something for that. Good luck on it Webslave, let me know if you have any questions about it. But make sure you tell your doctor if you feel anything that you aren't comfortable with. And thanks for the link. That's a great site! Kellie, that happened to me only once, but it was because I burned my lungs cleaning up a Clorox spill. My lungs hurt for at least a week afterwards. Scariest feeling I ever had. Hopefully you won't go through that again, but do tell your doc.
