Thanks for the tips. I'll try some yogurt later.
It's not that i have anything else like a flu/cold (i dont even remember the last time i had it), it's just this throat ache. My nose is OK. The problem is that here the temperature varies a lot during the day/night, so i might go to sleep and it's warm and when i wake up the temperature is already very low, and that gave me the throat ache today. And it still didnt go away, but i guess by tomorrow i'll be OK
