A couple of thoughts- Issabella- I am guessing you are Quebequois? If English is your second language, it might take a little longer for the paraliminals to sink in. Not a lot longer, but a few more listenings at first.
The other thing I was thinking about is how important it is to phrase your objective for listening. Say it in the positive- for example say "I will choose smaller portions" instead of "I will not eat too much" Your mind will hear "not" as "is"- so this is very important.
