I use indicas for pain and to help fall asleep. If im having a bad day and need cheering up ill use a hybrid or a sativa.

I have yet to use a strain that didnt give me munchies.

Yes alot of people get very uncomfortable with strong sativas. The heart race and uncontroled thoughts freak alot of people out.

In my experience the sativas, or high % sativas, are much stronger than indicas.
