Rixa.......I think you could be my twin with your thinking. That darned scale can put me in a tail-spin faster than anything else. It also wipes my good attitude right out of the window. I am weighing but only on Saturday mornings and I'm really trying not to let it bother me.
I think you have a very good plan in place. Like you said, stick to those maintanence calories and see what happens. I'm eating 1617 on non-lifting days and 1887 for my lifting days. What are your ranges on maintanence? I'll be interested to see how you do after a few weeks at that range.
Also, remember, have you taken before photos? Have you taken recent ones? Maybe doing that will get you "believing" again.
Hang in there. You are doing so awesome!! You just have to give your body a chance to catch up to what you are doing.
