I've had it for about ten years
I'm a 72 year old man with COPD. So about 5 years ago while In hospital for COPD, I learnt about potassium and bananas being one of the many fruits that have it. And when I choose my meals, instead of ice cream for dessert I picked banana. And to this day, before I go to sleep I always have the biggest freshest one I can find. And I swear by them. I also tried potassium pills from the web and they also did the trick, but I had to stop them as they interfered with my breathing because of the copd. But I found out on Google there are some fruits that contain a lot more potassium than bananas. Give one or two a try. You never know! Good luck.
