1.e4 is a fantastic opening, but it's definitly the most used (and thus most known) opening by a landslide. I'd recommend the Barcza to King's Indian Attack if you're looking for a change of pace.
I already mapped out the moves in this post if you'd like to check it out and give it a try
Let me know your results 
I feel that you shouldn't switch your typical opening just because everyone else plays it. However, if you are looking to throw off an opponent, playing 1.d4 and the openings that emerge from it works if you are more familiar with the territory. My classmates strictly play 1.e4, so 1.d4 presents them with a challenge before they even play. However, I'm sure players of your level will be somewhat familiar with 1.d4, so it comes down to who blunders/overlooks a certain move, or who has studied more of the variations that emerge.
Good luck to you!
e4: The best by test.
Saw Bobby Fischer
. 1. d4 is considered to have a higher win probability for white than 1. e4 because of the strength of the sicilian defenses. And besides, if you only stick with openings that are familiar, how do you learn something new?
The point is, that black can respond to 1. e4 with the sicilian defense, a very powerful opening whereas responses to 1. d4 debatably aren't quite as powerful.
If you don't want to play 1.e4 because it's popular, then why not to play 1.h4? I bet there aren't so much games with this opening!
Ok, joking apart: 1.d4 is not a bad choice, but you can always play the English opening 1.c4, or if you prefer even more strange openings, then 1.b4, which provides lots of tactical traps.
You may also consider 1. f4 (the Bird's opening) then, since that's an even less played opening but also decent enough to win games with. The positions arising after 1. f4 are mainly the From's Gambit (1. f4 e5 2. fxe5 d6), the reversed Dutch (playing the Dutch Defence but with an extra tempo! - 1. f4 d5), and sometimes play transposes to a good version of the Grand Prix Sicilian or a Closed Sicilian. So if you like those openings, you could consider playing the Bird's.
1.e4 is best by test
Since everybody seems to like 1.e4, I am considering stopping. That way, may be I will win more because people don't focus on the other Openings as much. What do you think?
