If your really desperate, load the back down and take it offroadin. I had an aal in my old toy tacoma and it sat about 2 inches higher. I put a couple of bags of sand in the rear for about 2 weeks and took it offroad for a while and it took it down about 1 inch. It just depends on what kind of aal you got, if it is a full aal then it will probably settle faster, but if it is a short one, its probably stiffer and might take longer.
