Protein for maintenance

Hi Everyone,
I have lost 148 pounds and am at my goal of 130 pounds I am maintaining my weight but I am puzzled.  I want to know if I need to still comsume as much protein as I had been when I was trying to lose weight?  I no longer go to my nut doc and my regular doctor doesn't know.  I have searched the internet and can not find anything on maintenance for weight loss surgery. 
Thank you,
Susan
