I'm wearing temporaries right now as well. It's been 11 days for me and, yeah at first, they really suck. I went back for 2 adjustments and finally got the bite correct. This helped a great deal but even so they still feel a little like wearing a mouth guard. Your bite however should feel natural even with the temporaries.
Either way, just do what I do and keep in mind that they're 'temporary'.
Going back to your restorative dentist to have more occlusal adjustment is avised.
