I am caffeine free. Drink decaffeinated tea and fruit squash. I started to do this when I was in hospital 10 years ago and they only used decaffeinated tea bags and because my sleep was terrible. Now I only need to have a tiny amount of anything with caffeine (e.g cola) and I am awake all night. No exaggeration I do not sleep at all. It is so inconvenient. When you go out for the night I never know what to have to drink (don't do alcohol either) and my job sees me in different places everyday with people asking "WOuld yo like a tea or a coffee" and me reluctantly turning it down every time even though I'd love one or even worse handing over my decaff tea bag. So how do I go about reintroducing it. I'd love a can of diet coke or to say yes to that cup of tea.
