Before being diagnosed I would drink both tea & coffee with a healthy slap of a teaspoon of sugar. After being diagnosed and shifting in to lchf, I stopped drinking both. It was good 8 or 10 weeks before I tried either, and I made an effort not to use sugar in either.
I found that tea with sweetner was too much, so now have a quarter or slightly less in tea.
With coffee i was incredibly surprised to find I could handle without any sugar at all. In fact if I accidentally slurp from the OH cup with sugar in it tastes foul to me. I expected it to be the opposite way round.
I have read that sometimes by not eating something you can 'reset' the tastebuds and your reaction. How true this is i am not entirely sure. It worked with coffee, and I have more appreciation for some foods. Sadly it has not worked for me and jelly babies, but could be worth a try!!
