I already use fluvoxamine which cant be combined with DXM, I am thinking of Huperzine A, memantine or agmatine sulphate as NMDA antagonist. I think huperzine should do, memantine is expensive and a complicated drug. Still need to read up on Agmatine I will take the taper approach and keep supps/meds to the lowest/simplest, thnx for your advice BTW: The diazepam was my doctors idea... I told them maybe
