Do what fits with your schedule. Some people suffer paralysis of analysis and end up doing nothing instead. I try and do a Litre of water with bicarb on a Friday Morning and break with the same on Sunday evening/Monday morning. That way I can still work and nothing too extreme so I can hang with the kids on the weekend. I don’t do it all the time and if I have a specific health issue I book the time off and get a week done. Easy does it ✌️
