Looking for advice regarding clover in my Bermuda lawn.

I used Celsius a few weeks ago to help control the clover in my lawn, and it did a really good job! I sprayed the entire lawn and after a couple of weeks, the clover disappeared. A month after spraying the clover and watching it die, it's come back. It is popping up all over my lawn and it looks like I'll have to spray all over again. Is this normal and expected? Will I have to spray every month to control the clover? Will the clover ever get too weak to come back?
