I was taking escitalopram and it worked fine- just suppressed my appetite. Dr recommended I switch to 10 mg citalopram so I did and took it for about a month. I just quit a few days ago and went back to escitalopram and the nausea is worse than ever. I often wake up with a heacache and my stomach feels like it is burning. The nausea is almost unbearable as well.
Another thing is that I missed my period (it's pretty irregular but it's almost 2 weeks late and I'm not pregnant)
