I used to drink an inhuman amount of caffeine. It made starting my meds kind of hard, because the caffeine started actually affecting me like it's supposed to.
So I was suddenly very jittery and nervous. For a bit I thought it was the medication, but then one day when I was making myself a cup of black tea I stopped and went, "...hey, wait, caffeine?"
Weening myself off of it was brutal. I started trying to drink one tea a day, then switched to green tea and very gradually decreased the amount of caffeine. I still occasionally get cravings, but luckily I can trick my body by drinking decaf tea.
It made me so fucking cranky, by the way, caffin withdrawal sucks.
If you're one of the few people with ADHD who can do that kind of intense hyperfocus torturing yourself into getting things done without being physically, mentally, and emotionally drained for far too long afterwards and also too traumatized by the ordeal to want to try it again, then good for you! Keep doing what works for you!
this mood is what i call "i need to get shit done" where you give the distraction gremlin in your brain candy in the form of music and caffeine whilst you desperately try to use the remaining resources in your brain to get work done because the deadline has entered "i can actually conceptualise this event happening" zone of the calendar and you're stressing out
I'm playing that game right now, but I think I need to turn up the music volume. I've heard the doom-style music ramp up during fights, but I haven't paid it much attention.
