Citalopram
"I was originally prescribed this for Major Depressive Disorder and Generalised Anxiety Disorder. At 20mg it didn't help at all, but once raised to 40mg and combined with an anti-psychotic (to prevent manic episodes) it worked well for 5 - 6 months.



Unfortunately it stopped working completely, quite out of the blue, and neither myself, other half or medical professionals could figure out why. It was a shame as  I had virtually no side-effects on this medication, just some 'bruxing' (teeth grinding) at night, but not to the point where my jaw ached or anything."
