I will only answer some of these questions.
1)Beef and pork are not allowed, primarily because they cause mucus production; mucoids protect the candida and your body can’t destroy them.
2)It can take as long as 6-18 months to fully recover from candida, so it will be very likely that you will still be on stage 1 when you go to this wedding (depending on when this is). I have been on the diet very strictly for 4 months now, and I only cheated for the first time a few weeks ago…I was able to handle these foods at this time, but not everyone will have recovered as well as I have.
3)you might not need the multi-vitamin, and there are many vitamins that you can take for health benefits. Undeceonic acid is another one that is popular. You can basically throw your money away taking as many anti-fungals as you want, but you most likely will want regular vitamins (read the recent vitamins post on the forum for some ideas). Whatever you take is up to you and your budget.
4)read response for question 2
5)goat cheese is probably something most can handle during stage 2, but I wouldn’t worry about that stage yet.
6)Candida can come back very easily depending on how ill you have been with it and how successfully you recover. I would be very wary of stopping the diet until you are symptom free. You feel so good again after the diet that you may not want to go back again.
7)Read the “dangers of die off” post. You most likely are experiencing die off and not the flu…you feel pretty awful during the die off stage.
