Even though I'd usually avoid it just to the caffeine and sugar giving me ADHD and Anxiety spikes, I'd go for the Irn BRU.
Woah, you don't want to be doing that to yourself Tash. Given how much it affects you, I'm happy to take one for the team here. Why don't you go for the packet of chocolate digestives and give them to me instead. That way you won't have any problems. Happy to help.
It only says "last snack on earth", you might be going up into space, and that would not be a good time to trigger ADHD and anxiety. Look I'm doing this for you mate, not me. Now just give me those bloody chocolate digestives.
You try to do the right thing for others and it just gets thrown back in your face (hopefully, if it's the chocolate digestives).
