I have used diuretics like hydrochlorothiazide when it gets bad with good results. But no more than once per week when it gets bad. I have to say that carbs (especially if I drink alcohol) and when I skip my 30 min of cardio at least 3 times per week, make it worse.
Just a warning to people about diuretics like hydrochlorothiazide, They can be very dangerous if not used properly! Be careful if venturing down this road.
