Mary,
if you need caffeine, look at it this way. Eat all the chocolate you want, dark or course, and wash it down with a cappuccino blast from Baskin Robbins (non fat but loaded with caffeine). The headache may suck
but the remedy
.
Truthfully, I'm sorry. I understand this headache is overwhelming. I can't believe they let a student 'practice' on you. Warning, next time, ask how many of the specific procedure the doctor has done before allowing him to touch you. It's your body and your pain and suffering. I'd also write a letter of complaint about the 'oops'.
