Never having taken any course of medication before I'm assuming that Citalopram is Citalopram, whichever brand it's badged under?
I've been using a brand new to me, 'Bristol' for a couple of weeks and it's either not as effective or I need to up the doseage. I've been on 10mg for about 9 months and it seems to do the job. I don't know if it's just coincidence but the recent slide coincides with this brand kicking-in (or not...).
Thanks - Andy
