Terrible to have free rein to eat as many calories as you want but to have messed up taste buds. :-( Hope they fix themselves soon!
O.M.Got as my little boy used to say, in a show of solidarity I will only eat a cheesy bean and rice burrito from Taco Bell for my work week lunch.
Maybe you need to go to an ice cream store that passes out samples on those little wooden spoons. Do a taste testing, go home with a gallon of the winner.
