I had an allergic reaction to something though for the live of me I couldn't tell you what and the doctor put me on benadryl, among other things. With anyone has ever taken it, you'll know it knocks you flat on your ass with drowsiness. And for those whom have the fortune of never having had to take it, they sell the generic form as a sleep aid.

So, yeah not much work is going to get done for a couple of days.
