I've suffered 3 major heart attacks in 2011-12, and my first one was in 1987 !!! I have sugar issues, and am on insulin since 2012. I guess my first cardiologist, in 2011, made my liver suffer by his whatnot poisonous meds he gave me! Then he immediately put me on insulin 50 units a/day when my blood-sugar never raised above 130, be it random, fasting or pp! Idiot...I could've been a multi millionaire if I'd sued him. Anyway, I am too kind a person to be a multi-millionaire!
Point is: Since then I am on no-sugar but eat-whatever I like diet, and am still alive 8 years later!
It's in your mind, dude! Detox yourself occasionally, but don't go overboard if you're not a baby. Point is, babies can be taught to be whatever in life, not us adults, especially where food is concerned. Also, if you want to go vegan, then don't ignore your body's signals. Go with the body than with the vegan food util it becomes healthy again to be abused. lol
Not a doctor's advice, get a real once is my advice, though I am already a registered doctor in my country...never practiced though, and went into sw, graphics, writing, etc; because I hated the side-effects of meds, and the un-ethics surrounded in the med field.
I now am a hobby practitioner -- homeopathy and acupressure fan and hobby practitioner...those who want to die they can come to me any day gladly!

None are dead! Most are alive and generally get well when I "treat" them!
The few people, friends and relatives, who come gladly to get the treatment happily agree to still continue it when I tell them that they can be dead if they take my more etherecal than modern
ethical treatment!
You see, I am certified to
kill them officially as a doctor, lol, but I am afraid that I might really kill them by giving official meds I am allowed to, hence the pseudo medical treatment which really benefits both -- they get well, miraculously, and I get praised if not paid (what's that?) ! lol
