Yep, that sounds like impatience to me

When your body does something dramatic like drop 12 lbs, it needs time to regroup and get used to the new lay of the land. The last thing you'd want to do right now, IMHO, is change something that has proven successful.

What you're going through is very common - both the 'pause' in loss and the impatience. Remember, is a WOL!!

Hang tight
