1. There isn't any recommended path after Terrain, unless you choose another Protocol, like a Cancer Protocol or the Morgellons and Lyme Protocol. The M&L Protocol is very good for eliminating many pathogens when it isn't known what all one is dealing with.
Doing anything can cause detox and healing, since the body may not be clearing out some pocket of toxin due to some pathogens living within the mass. One of the keys to healing fully is getting all of the processes in the right order so progress continues. It is hard for anyone to tell you what order things need to happen.
2. The Terrain program is a good one to run for a second time. But I would add another detox program along with it and be sure to drink a lot of water. It takes water to get the poisons out of your body otherwise it will accumulate in areas you don't want. I would also suggest going on a gluten-free diet for a month or so I have been on that diet for 28 years. The reason for you going on it is gluten causes inflammation which is what you want to get rid of.
