I set about 10 over a 20 minute period. Wakes everyone in the house up but me. I had a Fitbit with a silent alarm which solved the issue but just couldn’t be arsed to charge it enough.

Yes, that’s me. I wake everyone else up other than me. I would solve so many of my problems, if I learnt to actually wake up to the alarm. Current idea is to just start going to bed ridiculously early
The only alarm that ever worked for me was this. It is as loud as a jet engine and comes with a vibrating plate for underneath your mattress. It wakes up everyone in your house and street though. Worth it if you’re sadistic like me 😂

Link please. I want it just to piss of my mates in the dormitory😂
Enjoy 😂 would love to hear about their reactions
