I suffer from recurrent bouts of depression. I stayed on a low dose of citalopram after recovering from my last episode thinking I would be able to increase it without the side effects if I started feeling low again. November last year I started upping my dose from 5 to 10 mg then 15mg. I finally saw my GP mid December who told me that I needed to be on 20mg at least as this is the therapeutic dose. I'm 8 weeks in on a therapeutic dose, I increased to 30 mg 2 weeks ago and he's told me to increase to 40 mg. But I feel no better. Anyone out there give me their advice. Should I carry on and give it longer on 40 mg?
