orange juice fasting

When fasting is it fine to add diffrent fruit in with the orange to give diffrent flavors or could this be a bad idea. second im looking for epsom salt and have no luck in health food stores ill have to keep looking I really dont want to buy it online. third during fasting should I keep taking same amount of LBB or ajust it, im in the thirty day pre-cleanse so im thinking to stick to 9 a day.
