My schedule now is that I work two long days in a row and the I'm off for five. (I work part-time) My long days are very long because I commute 70 miles on each side of a 12 hour shift.
EVERY SINGLE TIME I work, I put on 3 to 5 pounds of water weight. Usually it takes a couple of days to shed the water weight, and then, if I'm going to see a loss, I see it... then BAM, back to work where I gain 3 to 5 pounds again.
Of course, I'm still seeing a net loss and I'm used to it, so I don't freak too much, but it still BUGS me.
I'm not sure if it's the four hours of driving in two days-- sometimes I sit a lot and sometimes I move around a lot while I'm there. I TRY to drink enough water, but I often feel like I get very dry when I'm there.
I'm kind of used to it, but I still hate it.
