This woe is no different in any other so far as how TOM affects us. If you typically retain some extra water weight, you're still going to. Perhaps you weren't as keenly aware of what has gone on before with it because you weren't watching as closely as you are now.
Aside from that, you're not going to see a loss every day, couple of days, every week and there may even be times where you don't see a loss for more than a month. It's ALL normal. This isn't magic and it's not going to happen over night.
But yes....TOM kicks my butt every month. He announces his impending arrival with a solid 2-3lb gain for me. *grrr*
