Upside down coaster question?

If you saw my other question, you'd know that I was terrified of going on an upside down roller coaster. Well, over the weekend I went to Hershey Park and rode my first upside down coaster-the sooperdooperlooper!! And I loved it!! JUST ONE QUESTION: During the loop, I felt my head being pullled down, gravity obviously. But if i were to go on another crazy upside down twisty thing (more than what the sooperdooperlooper was), would I feel that same effect whenever I go upside down? I ask this because I'm going to disney world over the summer and I'm deciding if i should go on rock n roller coaster or not. help please? thanks
