I think it's something to do with the time of year -- a lot of the recent threads here seem to be about how people are struggling.
Ditto. I have been having trouble keeping stable inside my maintainance range. I don't know why, but there are definitely certain times of year that are major struggles. I think the last time I felt like this was February... Then are are times when it seems like "this is so easy, I could do this forever no problem."
