Politics! I'm doing it at the moment and it's really good! It complements History really well, too, and is really relevant to doing an IR degree.
Economics is extremely mathematical, and complex maths at that. Since September, I haven't stopped learning about graphs, and only graphs. There have been 2 graphs, and about 10 variations of them. If you don't like graphs, DO NOT DO Economics.
Good luck.
P.S. Do politics!
