I took ketamine orally for about 3 years, it worked pretty well. Then I started getting ketamine infusions. I go into full remission immediately after them for about 6 months at a time. Then i get another. After the infusion I take no pain meds, until the pain starts to come back, just until i'm able to get another infusion. For 2 weeks after the infusion I take booster k pills in the morning and at night, and ativan or seroquel at night to help sleep w/o hallucinations. I've never had bad hallucinations, just constant music in my head or in the dark the textured ceiling will morph into various things. haha i think its entertaining cause i'm aware of whats going on.
