Things I did to manage bloat.
1+ gallon of WATER per day (if you need to add something I suggest Propel powder)
1x stool softener (dulcolax generic from Costco is very cheap) every morning and night
400+mg magnesium before bed
V8 juice 2 full 8oz glasses per day
EXTRA fresh, uncooked fruit and veg when on cycle
If it gets real bad, you can use wheat dextrin to move things along. For me, keeping myself well hydrated and making sure the food is flowing makes a huge difference. Also, getting enough, but not too much salt is important, though some will argue that a bit of extra salt is good on cycle.
