I'm with Jackdaw on this. I was on it for about 6 months and i became so lethargic it was unbelievable. I couldn't concentrate properly and even the most mundane of tasks became a battle of willpower. I weaned myself off them, taking one every 2 days, then 3, etc, etc. After about 3 weeks i began to feel better, though still very depressed at times. I still suffer depression and have bouts of anxiety in the company of strangers or in unfamiliar surroundings, but, in my own little way, i am coping.
