I found the best way to replenish minerals/electrolytes after a Liver Flush is fresh made juice (not store bought). Are you juicing? If not you should invest in a juicer and start. I found a really good mix is beet, carrot, celery, cucumber, ginger, and lemon. Also coconut water is good for potassium.
Do you drink at least half your bodyweight in ounces of water/juice per day?
Are you supporting the liver and building healthy free flowing bile in between each flush?
Are you doing some bowel cleansing like P&B shakes and fiber in between each flush?
I found for me personally the best way to do the Liver Flushes is to completly skip Epsom Salt dose 3 and 4, and instead do a few water/salt/bentonite enemas instead. So epsom dose 1 and 2 as normal, but no dose 3 and 4 but enemas instead. I found this way to be way less harsh on the kidneys so there was no kidney aches for the days following the flush. Doing it this way is allowing me to do a Liver Flush once a week as long as I drink fresh juice, Bowel Cleanse in between (P&B shakes), and focus on building up healthy bile in between with specific supps. and foods.
