I'm a few months further into this, and I've seen myself go through a couple of "slumps" if you can even call it that. It's kinda like an ebb and flow to me. Right around my 7th month or so, the holidays came up and I spent a lot of time with family, did a few splurges, got out of my routine a bit. The beautiful thing was, even though I considered it a "slump", I definitely didn't gain at all, still continued to lose, just a little slower. Got my mojo going strong again at the beginning of the year, lost well for a couple months, then another little bump in the road lately. I've still continued to lose the last few weeks, just not as gung-ho. And now I'm back at it full force and ready for another couple months of great losses.
Life happens, and for me, I have to be honest that every single second of my life is not going to consist of doing the perfectly right thing. I am human after all, and sometimes I need to back off just a little. BUT, I kinda consider it practicing, because not once have I thrown it all away and gone back to my old ways. I'm in no hurry, I don't make strict timelines for my loss, I'm really trying (and succeeding) at finding a lifestyle that makes me happy, relaxed, excited, and occasionally lazy, all while losing all this extra weight.
Let's make these months coming up to summer really good ones!
