I had mine out when I was 25 and I survived it just fine. I was actually nursing my daughter at the time, so I did not take many pain meds. Mine was also outpatient.
My hubby had his done last Feb and he was feeling better within a week (he also had some soft palate removed and turbinate surgery for sleep apnea reasons done at the same time, so his was even more intense!)
My best advice is to have LOTS of things on hand in the house to drink and eat- from soda, to bottled or pitchers of cold water, extra ice made or bagged, juices, Gatorade in different flavors, etc. Jello, chicken or other broth soups, instant mashed potatoes, applesauce, etc.
I prefered things room temp when I had mine out, my hubby prefered cold things. Another thing you can do is ask for an ice pack that can wrap around your neck (they can give you one at the clinic) and you can ask your dr for a prescription for pain lollipops too- my daughter used these when she had hers out and they really seemed to help. It is basically Morphine in lollipop form (hers were grape!) and you can suck on them for 30 seconds to relieve pain immediately.
It's not as bad as people make it out to be, and all 3 of us have benefitted from our surgeries GREATLY- my hubby has decreased snoring probs and better night breathing, my daughter and I have decreased allergy symptoms and less sore throats.
My surgeon did tell me that for adults, expect *some* residual sore throat pain off and on for a year because it is VERY slow healing, so don't expect to be sore-throat-free overnight :(
Good luck!
