LOL! Yes, there is a shot for that, in fact it's a series of 2 (Shingrix vaccine). I actually got mine a couple of years back. Definitely get it, if you're "old enough"...last thing you would want is to suffer getting shingles! Apparently it's quite effective.
Hahaha! Have gotten several of those over the years (no, not due to age, but have to get them more often due to history of colitis). I can deal with an all-liquid diet the day before, I can deal with the procedure itself (since they knock you out for that anyhow), and I can deal with the "recovery" right afterward, plus I can eat normally again at that point. But the ONE thing I just CANNOT get used to is that God-awful gallon of prep solution you have to drink the night before. Ugh! It is awful. 8 ounce glass every 10 minutes. It's like a bad drinking game! I can be fine for the first 3 or 4 glasses, but after that it gets to be a real struggle. Even the "flavor packs" they give you don't help much...still tastes like disgusting metallic salt. Bleahhhhhhh!
