Since cutting out a lot of the salt I'd been consuming I haven't had any problems with TOM bloat. I eat very little in the sweetener category as well, which I believe is suppose to help. I know it's hard, but cutting down on salt and sugar really help (I routinely consume less than 2000mg of sodium per day.)
As I recall, Midol didn't help with the actually bloating, but it helped with the pain that is associated with the bloat. I haven't taken it in awhile, but that's what I remember.
Time to lose the baby weight!
