Now I know it says that we shouldn't eat chocolate because of the caffine in it and I've been doing good with it but does this mean hot chocolate too? And how about chocolate milk?

Here is some info from UCLA:

Hi
Chocolate doesn't seem to bother me.
When I really want some I eat just a little bit.
Your body will tell you if you have had too much and then you can start adjusting the amount you eat. For example, maybe you can tolerate a 1/2 cup of hot chocolate instead of the whole cup.
I don't think you need to cut it out 100% unless even the smallest amounts bother you.
