Morning,
My experience is a bit like yours, I took citalopram about 4 years ago for the first time having had a break down. I thought my anxiety increase was related to my health but, in hindsight, having taken it now for the second time I would feel pretty confident in saying that my increase in anxiety, initially, was due to the tabs.
Luckily when I recommenced taking 20mg of citalopram back in dec '10, I was off work on holiday and was absolutely in pieces, a mess, I cant describe how terrible I felt. But, after a couple of weeks off work these side effects decreased quite quickly.
There is no way in this world that I could have gone to work, I laid in my bed for many a day...
I am still on citalopram and quite happy in life, not sure how much of my feeling good is down to the medication or me, myself.
Hope you feel better soon.
Jackie
