I'm assuming yr bloat doesn't have a medical reason. Being bloated can be a sympton you need to check out with yr GP.
Ring your counsellor - she will have some advice - that's what you pay for! My advice is set a reminder for yr three times for shakes and drink your shake before you drink the next water and/or reduce yr water to 2.25 litres. Someone on the CD forum or exante etc here may have more advice.
