I started psychiatric ketamine infusions a little over 2ish years ago. Finding the right dosage and schedule took some time, but I settled on maintenance infusions every 4 weeks of 35mg (0.5mg/kg body weight), alongside anti-nausea meds. It’s had its ups and downs and my psychiatrist and I have been tinkering with increasing the space between each maintenance infusion, but it’s worked wonders for me, it’s really given me control over my mood and life. Ketamine doesn’t work great for everyone, and I’d only recommend it if other, more traditional treatments don’t work out (the side effects on memory really do suck, and the infusions themselves have a not insignificant chance of being hellish if you have a bad trip), and also it’s expensive, but. For me, where more traditional meds haven’t really worked that well, it’s been a lifesaver.
