What do you mean "tried" it? I used to get that shit from Starbucks with a shot of hazelnut. Shit was delicious. That was during my youthful high school days.
Before that, I was breast-fed. So yes, I've tried warm milk.
Do you mean for sleep? Like will this somehow lull me to sleep? Because I have to go through the whole process of warming it up. And when I'm up in the middle of the night with no sleep, my motor skills are impaired.
This leaves me with having to worry about two things: 1. Exploding milk in the microwave. 2. Third-degree burns from milk up-splash from cooking it on the stove.
Let's say I get the milk warm successfully. I am old now. Lactose is just not the same as it used to be.
Have you ever farted yourself awake?
