I was lucky and managed to leave one of my pokemon on a gym that lasted for 4 days this weekend... But other than that I normally get kicked off a gym within hours around here, if that...

Have you been moving around while having your incense on? If you are walking you are much more likely to come across pokemon than if you are just sat somewhere... The optimal speed for pokemon to spawn with incense going is around 6mph apparently...
