I have been having a lot of leg and toe muscle cramps lately, especially at night, but also some during the day. I do take Benicar HCT 40, but have been taking it for 1 1/2 years. Could this be related, as it has a diuretic? Also, could this mean I need more potassium. The last couple of days I have had bananas and canteloupe and less cramps.
