anxiety and stress
"Took successfully in 2003-4 for PTSD and associated anxiety. No side effects (other than lost libido) and came off them easily under doctor's supervision.

13 years later I was put back on them due to depression and anxiety. This time they have been horrendous! 

Headaches, bones in my face aching, nausea, a"creeping" feeling through my hands, arms and shoulders, disorientation, racing heart, not passing urine frequently enough and terrifying sleep problems (insomnia but feeling like you're being suffocated and having awful thoughts). 

After 12 days I realised I couldn't take these symptoms any more, on advice of a doctor I ceased instantly, by Day 2 the withdrawal was awful-a more intense version of the side effects. Easing now (day 4)"
