i am not a doctor, you should probably ignore me.
are you feeling the combined effects of a citalopram plus winter darkness? (both of these monkey around with serotonin levels)
could you see more daylight? / use a lightbox?
what’s your dose? – like any medication it’s probably not a bad idea to be on the lowest dose that still works, but some doctors seem quite happy dishing out 40mg doses – i’ve seen this dose turn friends into zombies. Would you consider slowly reducing your dose to see if you can control your symptoms with less?
