Indica's give more of a body stone, where you may get sleepy, feel extremely relaxed and blissfull, and just peaceful.
Sativa's will make you silly, more of a trippy, "woaahh..." high, more of a mind high.

Most people have their favorites, but alot of people prefer a cross of the two, so they get the highs from both of the strains. Most weed available today is a cross between the two.

Also, sativas are generally lighter green in color, as the plant uses less chlorophil, and tend to have a fruity, sweet, smell.

Indicas on the other hand are usually dark green, and smell VERY skunky.

It seems, from what you described, that you have a sativa predominant strain, but I may be wrong.

But, it looks like you'd like a nice indica.
Good luck!
Peace,
