I feel this question is different for low bmi'ers that is why it is here.

Wondering.... when should I get a fill they say between 6 and 8 weeks, but what if I don't need one?

I am flying back to TJ Mexico for my fills and tickets are cheap if I buy far in advance. I am afraid I will buy a ticket and then not need to go yet.....????

Any advice out there on this?

Well, statistically speaking, most Banders need fills to get restriction. Is flying there really cheaper than finding a place to fill here though?
