I have been meaning to post something for a while as almost a heads up for anyone searching for Citalopram and Green Tea!
You are not alone, I too feel very ill if I take Green Tea tablets!
I was doing some research and according to a couple of sources, Green Tea is listed as something to use with caution.
I have made the mistake of taking Green Tea tablets twice since being on Citalopram and I would not recommend it, both times I have felt incredibly sick, almost like the feeling you get with food poisoning, and started to sweat an absolute tonne.
I am unaware of anything like Green Tea that I take that would leave me feeling so sick!
