You may develop tolerance to Isonit with time, meaning that the same dose may be less effective next time. Follow the prescribed dosing schedule to avoid this. Eat healthy (low-fat, high-fibre, low-sodium diet), quit smoking, limit alcohol intake, increase your physical activity, watch your weight, and reduce stress.
