I went beserk when I went off Cymbalta (cold turkey, dumb I know...). I know it is a different type of drug, but they mess with brain chemicals nonetheless. Benadryl, due to its sedative qualities, in OTC doses did wonders for some of my symptoms. It didn't help the nausea, but really helped calm the symptoms of sedation, stomach upset, hot flashes, and general stupidity.
