That would be comparable with asking someone who smokes weed a couple of times a year to quit cold turkey.
Of course it’s not going to make any difference to you if you stop taking sugar or not.
However ask someone who “needs” to have that redbull every day. Who drinks sugary lattes, eats sweetened bread and so on.
Ask them to quit and they will most likely experience withdrawal symptoms and have a really hard time to keep away from sugar.
I just slap on a hair wrap and let the hair dry by itself.
