Potassium problems - Please Help

Jeanette, I had (and may still as they are trying to weene me off) p[ostassium issues. My doctor put me on a liquid supplament as bananas are high in sugar as well and he did not want me eating a lot of them. The liquid is GROSS and must be diluted but I learned from a nurse in the hospital that some of the sugar free cranberry based Crystal lite is strong enough to mask it a great deal (and it was as I had to take it for about 2 months). Is this a possibility?
