Stop toying with me scale

So last week I failed to make as many strides as I had hoped. I weighed in this morning at 216.5, which is still up from the previous week. Yesterday morning I was completely famished and dehydrated and weighed 215. Which was exciting but not healthy, as it was brought on by a night of heavy drinking. I also failed to do any cardio last week so this week I plan on rekindling my like-hate with my elliptical machine, and weather permitting my bicycle<*gasp>.
