I can find no definitions accept trial and error regarding anti depressants for Multiple Sclerosis patients, and have tried several that simply do not work for me with my MS depression(s). What has anyone with MS had success with, as even neurologists do not seem to have best answers? Another words, strong "picks you up" anti depressant a.k.a. Paxil which worked but required increase of dosages to limits and had terrible withdrawal symptoms.
