RE: tonsilectomy....
I am 37 too, had my tonsils out at age 26, I think it was. Kept getting strep after strep after strep and finally said "enough!". It was outpatient surgery for me. I think it was 3-4 weeks before they told me I would be able to lift weights again.
I would say definitely listen to your doctor. I ended up having a hemorrage in my throat (not related to working out, I hadn't started back yet...it was just one of those things)...basically the incisions in my tonsillectomy site started to bleed, I woke up early one morning 2 WEEKS post op feeling like I had something I needed to hock up in the back of my throat, kept trying to swallow it. This was the day I was supposed to be back to work, even!! I proceeded to begin throwing it all up (blood irritates your tum)...nasty business. Several bouts of that within the hour, before it clotted up and I was able to drive myself to the doc and was taken back in for surgery and they put a stitch in. Doc says it is only 1percent or so that that happens to but you do NOT want it to be you. Don't lift weights until they clear you...the exertion too early I would think could cause something similar. This happened the day I was supposed to return to work so I would have thought I was all clear. Don't mean to scare you or gross you out, but the only thing worse than an adult tonsillectomy...is TWO adult tonsillectomies! Just make sure you listen to the doc....if he says it is OK, I would think it is.
By the way it is the best thing I ever did, despite the complications....I have hardly had a sore throat since. It is AWESOME.
I wish you a very smooth recovery! I would lay on my couch watching all those food commercials! Did you ever notice how many food commercials there are on daytime tv?!?! Seems like all my throat could handle was puddings etc. but after a while it was like...sheesh, gimme something crunchy and salty!!!!
I think I did lose some weight....but then proceeded to be so starving and dying for crackers etc. when I could eat that I gained it back.
