I'm 53 and just had mine out the old fashioned way in June of this year. Even though it wasn't coblation, it was very "doable" with the right combinations of meds. My doc prescribed cortizone, an antibiodic, a med for thrush, a liquid numbing medicine, and a pill that was a combination of demerol and phenegran (for naueau). I had to call and ask for lortab as the demerol was not strong enough, but really helped because it had the anti-nausea med in it. I found that I didn't have most of the problems others experienced such as swelling because of the cortizone, etc..
Don't worry about being 45...you're still a baby!
Seriously, it was the best thing I ever did and would do it again in a heartbeat if they freakishly grew back. Before having my tonsils out, I seriously thought it was normal for my throat to hurt each time I swallowed.
The site that Jimmyhonda mentioned above is really great....it'll help you a lot. The last time I looked at it, there were several who had the coblation technique so I'm sure you'll pick up a lot of good tips and info.
Good luck and by all means go for it....you'll be glad you did!
