I would advise niacin supplementation and intermittent dry fasting or water restriction (see ‘the dehydration treatment of epilepsy’ in the research thread).
Regarding diet, a high cholesterol diet might help.
I came off antidepressants and had horrible side effects for a long time. A 14 day water fast with nothing but water and salt cured the neuropathic symptoms. Dry fasting would also help however, neurological regeneration is as potent with water fasting and water fasting would facilitate the ability to take more and safer, light exercise throughout which would also be beneficial imo. I’d try 10-14 days water first, brief refeed for a few days then shoot for an extended dry fast and cement/polish your results. Obviously do so safely and be prepared for your symptoms to increase markedly in the fast before they improve/clear
