Thanks for the advice. Living in a country currently where I very much doubt I can get naltrexone from a shrink but will look into it.
I didn't have much hope for the SSRIs but decided to respect my first shrinks expertise and go along with it thinking I had nothing to lose.
Reawakened my dormant HPPD symptoms and did nothing to diminish my paranoia/DP etc. which I've had ever since I went on a major drinking binge last August. Used to have these feelings for a day or two. Now it's been 8 months or so.
No clue why. The lamictal not helping made me jump on the NMDA theory but maybe I'm chasing rainbows.
Did try kava capsules to little effect. Perhaps the teas or tinctures etc. might be worth a shot.
