When I was much younger, I remember ones on tables that tilted from side to side, and were much more uncomfortable than one I had six years ago. I think that Benadryl was the primary thing they gave me to make me drowsy. But I did decide to scratch my nose at one point and had them all jumping. Whoops. Don't move.
When you were a kid, you probably had an incision. Now they can do it all through two small holes. This last time, I had to lay with a weight on my leg until late in the evening, and ended up having to spend the night at the hospital.
BTW, I have a question also: After the last one, and maybe the last two, I suddenly got very cold and chilled and very shakey. Has anyone else had that happen?
