So I dont have access to pharma PDE4i's nor am I planning on acquiring them in the short run, but I found it striking that eating grapes (resveratrol?) has a distinct anti-depressant effect on me, somewhat similar to what luteolin had on me which is also claimed to be a PDE4i.
Feels like a mix of a SSRI and beta agonist to me, pretty amazing effect tbh, I cant believe there is not much if any talk at all about this.
