I’ve had my pm for five months and have had an issue of energy when playing Pickleball. I’m trying to determine if it’s old age (81), incorrect eating habits of low energy foods, physical conditioning, or needing pm recalibration. I play highly competitive three days a week and used to play 4/5 days a week before moving to current location. My issue I just seem to lose energy and get weakness after playing the first game and it gets worse the more I play. I seemed to notice this since getting my pm. Would recalibration of the pm help. I make sure I eat carbs and protein for energy. After playing I sit down and recoup and feel good. Any suggestions?
