I was on 30mg, been taking this or 20mg for 4 years. I was prescribed it as I had very severe pnd and was suicidal. Anyway, I feel well, have for quite a while. 3 months ago I started tapering off my dose until I got down to about 5mg a day. I stopped entirely 5 days ago. The dizziness and strange sensation in my head are driving me crazy. Anyone know how long it's likely to last? I'm trying not to take anymore citalopram and to ride it out but it's so hard! Thank you.
