its all down strokes, i actually dont think theres a single up stroke in the whole song...

it varies a lot throughout, but for a lot of it its just strum every beat 1, 2, 3, 4, 1, 2, 3, 4 ...
on the 1,2 and 4 play only the upper 2 of the strings in the chord, and on the 3rd beat, play 3 strings.
so for example, if your chord is:


the 1, 2, 4 beats will only play the A and D strings, and the 3 will play A, D, and G

im pretty sure the main changes throughout the song is just which of beats play 2 strings and which play 3. i havent heard the whole song in quite a while though.
hope that helps

edit: its actually two strums per beat if youre counting correctly
