Best results are achieved if you don’t exercise before your session and fast for 2 hours before and after. Drink a gallon of water in the 24 hours prior to your session. You’ll need to increase your water intake to at least 2 liters per day to ensure flushing the cellular waste from your system. Expect to use the restroom slightly more often while completing your sessions and may find darker urine.(Nothing crazy, just a little darker) Your treated area may stay pink and feel cold for a few minutes up to a few hours following. Wear loose clothing and undergarments.
