3rd Hangover in 3 Years

I have a headache, I’ve only had a few hours sleep, I’m dehydrated, and a little fed up. Why did I go and do that again? I’ve gotten drunk 3 times in 3 years. I suspect that was my last time. It’s not big and it’s not clever. I’m not entirely sure I like who I am when I drink. There are small elements I prefer, I have insane levels of confidence, I feel brash, etc. but there are much larger downsides. I am a bit of a plonker, worse I’m not very nice to people. I hereby resolve not to drink alcohol again at least for 12 months.
