I'm in pretty much the same place guys - 54 lbs. gone, but now it is coming off verrry slowwly...
It does suck, but I think it's part of the process! We are in this for the long haul, and happy days will be here again eventually.
I suggest sticking it out, don't stress over the scale, keep working on the exercise, and look at your eating to see if there are any little areas you are slipping and need to tighten up a bit. And if you are hungry in the evening and want your snack, by all means, have it! You did say "snackS" though, so if you are eating a lot in the evening because you're hungry, maybe try eating more earlier in the day. I eat a BIG breakfast, snack, substantial lunch, another snack, pretty much every day, with lots of protein, and it helps because by dinner time, I'm not all that hungry for the rest of the day.
Life's a journey, not a destination.
It's easier to stay on plan than to get back on plan.
