When you go to maintenance, your target will be higher than it is right now. I would suggest slowly adding in some flex points on top of that. Try to get in 4 a week the first week. Then 6 the next. You can keep going until you get to a point where maybe you have a little of a gain that week. Then back off to the number you were using the previous week and try to stick with that. Those flex points are there for a reason

You don't HAVE to eat them, but you are probably being really restrictive if you aren't eating any of them at all!
