So i had my test yesterday. Instead of drinking that liquid they give you in one hour i had to drink the milk.
Every 15 minutes i had to finish a glass. After the 2nd one it was already getting though so imagine after the 4th one. I tried not to throw up. Best is to drink slowly. But if you're lactose intolerant then you better skip it.
Other than that everything else was the same.
Oh and i did have to take 4 pills of Dulcolax the day before. It went well also. Wasn't too bad.
