I've stumbled onto the discovery that Zantac, which I'd been taking for severe acid reflux, seems to help my post-crapalta anxiety ... did some research, and found a number of old (really old) articles that seem to confirm this ... here's one of the freely available ones ...
Caveat: but be aware that new research is showing that extended use of Zantac, and / or use of the highest dose, may cause kidney/liver damage.
Effect of the H2-receptor antagonist ranitidine on depression and anxiety in duodenal ulcer patients
Depression and anxiety were measured during the course of a double-blind, placebo-controlled trial
of the histamine H2-receptor antagonist, ranitidine (150 mg twice daily), in patients suffering from
duodenal ulcer but free of systemic disease. There were 25 patients in the ranitidine group (mean age: 33-2 years) and 28 in the placebo group (mean age: 37-2 years). In both groups there was a highly significant and progressive decrease in depression and anxiety scores over the 4 weeks of treatment. There were no instances of mental confusion. In our group of otherwise physically healthy patients, ranitidine appeared to be free of neuropsychiatric complications.
