2 months ago my dermatologist prescribed me Elidel to pretty much use until my lips get better, but it wasn't doing anything. So after using it for a month, I asked for Protopic instead, and lo and behold a few weeks later peeling just completely stopped.
I don't think I have ever reached this point as far as EC goes, and I've had it for about 6 years now. I don't see myself stopping Protopic anytime soon since my lips are still a bit inflamed and get irritated easily, but the swelling has gone down as well.
Really recommend trying Protopic. It does have an unpleasant sensation the first few days with burning/stinging etc. but definitely worth trying :)
