Dear Dr. Gott,
It gives me great satisfaction to donate blood but the last two times (over a period of a year and a half or so) , I have vomited during the process. I am a healthy 51 year old female and the only meds I take are 40mg. Micardis (daily). Before the procedure, I am sure to be well hydrated and have a good meal. What can I do to prevent this from happening again? Should I continue to donate?
