My primary symptom has always been anxiety and panic, which led to DR (not DP). The DR faded away on it's own, pre-medication, over about a year.
Here's a list of all the shit I've taken over the years for anxiety and panic. I've never really suffered from depression:
Anafranil - 1 tablet, terrible side effects. Stopped immediately.
Cipramil (Celexa) - No side effects, possible dampening down of anxiety. Pretty rough withdrawal.
Respiridone (Restoril - a goddam anti-psychotic) - Nasty side effects, no effects on anxiety. Walking zombie. No withdrawal symptoms.
Effexor (Venflaxatine) - No side effects, slight lightening of mood, definate (but mild) dampening of anxiety....haven't had a panic attack in two months.
Diazepam/Oxazepam/Lorazepam - The only thing that totally cured my anxiety and panic - totally and utterly. Only temporarily of course. Strangely, although I've intermittently used fairly hefty doses over the past four years, no withdrawal at all.
Propanalol (Beta-blocker) - Possible, very slight dampening of anxiety. No withdrawal.
Valerian (Herbal anti-anxiety) - No side effects, absolutely no effect on anxiety, even on mega-ultra high doses. No withdrawal
Chinese Herbal Medication for anxiety. - No side effects, absolutely no effect on anxiety, even on mega-ultra high does. No withdrawal.
