I was on
Xanax for four years, low-dose (between .25 and 1.25mg/day) but steady, for insomnia. About 21 months ago I experienced a comprehensive mental and physical health crash that included, but was not limited to, severe depersonalization, dizziness, fatigue, anhedonia (probably the worst feeling of all but I'm glad I found a word to describe it), pressure-like headaches, palpitations, cognitive fog, trembling, and a savagely blunted memory.
