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.
