You know youve got me thinking when I used to eat my favourite sweets Haribo (the jellies) or a boiled sweet. my tounge would become very sore, it looked like it had been burnt with blisters and have my taste buds where missing, ( I was worse with the super sour ones, they where cover in sugar!!) I thought it was just a reaction to the e number or colourings, now I am wondering if it was sugar!!
