I made it around 7 years Vegan. Then it had to stop. Between alcohol usage and heavy carbohydrate intake in general, I found myself with some major problems. It got to the point where even during periods of total alcohol abstinence (for example, 60 days). my body was not processing carbs well - even from "healthy" things like fruit. I developed nerve damage in a foot that was excruciatingly painful and would keep me up nights in intense pain. That damage is still there, but substantially lessened after only 3 weeks on a diet of mostly:
Meat: Pork products, beef, fish, Turkey, eggs etc
Fat: Meat-fat, Ghee, butter, MCT oil, fish oil.
Sauerkraut.
Very low carb intake (0 sugar, sweets, very small amounts of carbs in general, only occasional bread)
No seed oils (Canola, Sunflower etc....anything that comes in a bottle that isn't animal fat) and especially no commercial fried food (seed oils are used for the majority of fried fast food).
No Fructose esp (contains carbs, but this is especially inflammatory - it will oxidize unstable fats like crazy....and industrial seed oils are unstable fats that have been destroyed but chemically made to taste and smell neutral). Table sugar is 1/2 Glucose, 1/2 Fructose so anyone eating any sugar (white, brown, etc) is getting Fructose into their body).
My former Vegan diet consisted of a ton of foods made with unstable seed oils, and these seed oils stay in the body for a long time and are oxidized quickly with glucose spikes, and even more so with the use of Fructose. The Vegan diet I followed was also a typical one that was mainly focused on Carbs for energy.
Keto, no seed oils, animal fat and meat has worked for me to heal from the damage I did as a Vegan over nearly 7 years. I haven't even stopped alcohol completely and there was still an improvement.
I came back here primarily to share this. I didn't want anyone to be encouraged by my experience into going Vegan long term. There's a lot of missing nutrients on it, not just B-12. One can live on it for a long time, but the deficiencies catch up eventually. The people I know in life all tell me I am looking much healthier now. My thinking is also clearer, mind doesn't race as much, and I can get better sleep.
I don't know why The Universe, The Gods, or God has helped me here, but whatever it was, I am grateful for the chance at living without the pain. This has actually been a catalyst (not the only one, but a big one) for me to look at other faiths and to better follow in the steps of my ancestors, who I have disregarded for many years. As such, I don't really belong here, so after a few hellos and goodbyes, I will take my leave again and go elsewhere.
Thank you for reading, and blessings to all on their journey through this life!
