i have quitted sugar , as such,  complettelly   for at least 15 years and
cut drastically for 25 years
I had a long episode ( may be 8 years )of high fruits intake but quitted to
no more than one fruit a day in average 4 years ago .
In general all my life i never been very attracted to sweets , i am a salt
person ( french charcuteries and cheeses and roasted peanuts were my treats
, snacks and meals also  )
