So i bought the RRO budget lift with out reading on here first. Mistake number 1!

So now that i have it installed i have noticed that my rear bounces alot as in like a lowered honda that you would see bouncing over every little bump. It is a fun ride at first but it is getting quite aggravating. What would be a suggestion to lessen the bounce until i can afford a proper lift. I am about to get out of the military so i am short on funds. I want to do the cheapest way right now. Any help will be appreciated.
