Thank you for the info. I've had potassium salts make me sick before, so I will still ask, but probably not an option. I will stick to the pineapple juice mixed with the diet soda. I am not even supposed to take multivitamins because of the kidneys, so I am pretty sure the kidney doc will say no. But it looks like I will be waiting until the 21 to see anyone anyway, my doc is taking 2 weeks for a medical thingy and can't schedule me until the week before that anyway. And honestly, with no way to transport my power chair, it just makes it too hard. If I could be seen next week like usual, it would be worth the effort. But I wrote down some of the advice in eating and drinking to refer to until I can get in.
