I'm 31 and had mine out four months ago.
I got referred easily by my dr (based on getting tonsillitis 3-4 times a year) and the consultant just ticked boxes and I got a date for 8 weeks later. Easy peasy.
I've never had an operation and was very scared and nervous. It was horrible going under. I bled a lot so had to stay overnight. And was nil by mouth for 36hrs so had a drip. It wasn't that bad, I was off my face on painkillers. My mouth felt battered and sore as if I'd been punched in the gob but eating at first wasn't bad.
I was on maternity leave with a 9 month old and also a 3 year old so my mum came and stayed for a few days to help and my husband WFH for 2 weeks. The care from others for at least 2 weeks is vital.
For me, swallowing and drinking was no worse than having tonsillitis. And I took paracetamol and codeine for about a week. A cold/hot compress and wearing a scarf helped loads, as did using a humidifier in the bedroom and just resting lots. Days 4-8 were the worst because of the ear and jaw pain. I've never even had a filling and have a low pain threshold. I couldn't eat because of the pain in my ears rather than my throat. I didn't wake up in the night in pain because of the humidifier.
I lost my sense of taste for about 3 months but took zinc tablets every day as that apparently helps.
I'm glad I had it done. The fear of getting tonsillitis and being debilitated always worried me and I always got it at important times eg holidays, my wedding, Christmas.
No lookin back for me. So relieved to know I'll never have tonsilitis again. No more tonsil stones. And I don't snore any more which my husband is thrilled about 
There's always horror stories and good stories. I would rather give birth than have a tonsillectomy again (& my babies topped 10lbs each) but it is definitely short term pain for long term gain; my advice would be get it done, push through the discomfort and then you can relish knowing you'll never suffer with tonsillitis again.
