cutting weight sucks

I started the season off in fairly good shape because of bjj I was 5"9' 175ish Iam down to 160 and Iam working my way down to 154. at 160 I have 8.5% body fat and I think ill be around 5% at 154. this sucks and I was just wondering if pro fighters cut much more then me (because I know I sure as hell cant make it any lighter then 154)
