I'm pretty much the same way. A couple of weigh ins ago I was up 4.4 pounds after a free for all week. I was good for most of the week after and I lost the same 4.4 pounds at my last weigh in. I learned from that and have been good since. Not saying I won't falter again but it should keep me on plan for awhile before it happens again
Just get back up on the high horse and try again.
