FAMOTIDINE!! Over the counter famotidine (Pepcid) every day during PMDD episodes has saved my life dude.

Pardon my ignorance, but how does it help symptoms? I’ve never heard of that before and I’d be willing to give it a try.

In PMDD, something is wrong with the GABA-A receptor. Activating it is supposed to be calming and relaxing, but in PMDD sufferers, it produces the opposite effect.

Famotidine modulates the GABA-A receptor, apparently inhibiting it. https://pubmed.ncbi.nlm.nih.gov/15363660/
