I found this helpful for my last fight. Its hard to do but works. GSP on cutting weight
Day of the fight I wanted to lose 3 lbs so I sat in a hot epsom salt bath and sucked on hard candy so I could spit ( I don't chew). Funny part was when I got to the scale it was 4 lbs light so I was supposed to be 155 and weighed in at 149.
Most importantly Have fun don't kill yourself cutting weight and not preform the way you want.
