I would not flush for about two or three months. I would try to time my first Liver Flush around the spring equinox/full moon time in the spring. It would give you time to prepare and make changes and most importantly, time to heal.
You could start now by taking detox tea....that will help you to get rid of the toxins from the surgery.
Take psyllium daily for your bowels. Read up on the P&B shakes too for future reference (links at top of page).
Even better to take, would be Dr Schulze #1 to get your bowels moving well.
Drink half your weight in ounces daily of pure water.
REad, read, read to make changes to the positive for your health.
