Fully recovery definately, i know a few members on here that are symptom free and have been for a while and am just really glad they still come on here very regulary to help others but they are still on restricted diets out of choice.
after 3 months of doing the diet i was pretty much symptom free, then due to a really rough time at home i hit the beer for like 2 weeks and then returned to eating normal food. i was fine the first 6-8 weeks with no symptoms apart from stomach/side pain but then slowly all the others returned. I think this was down to the fact i hadnt killed the infestation off from before and didnt continue probiotics and ate normal again.
But, i reckon that as long as you kill it all off properly and continue high strain/count probiotics and make wise choices like pina said and introduce everything as ‘test items’ then i cant see how it cant be done. But like Pina also said i dont think youll want to go back to the old way of eating. once everything is under control and has been for a while then maybe a few beers/a cake/sweets etc every once in a while is plausable, assuming you dont go back to the old ways.
i dunno, just my guess.
