I am impressed with her dedication so far. I have seen nausea too but the onset here might point more to the antibiotics and the Herximer-like reaction whenever she takes them. Remember most antibiotics are broad spectrum enought to kill a lot of gut flora and release the enteric toxin product of this kill through her leaky intestinal mucosa and into the bloodstream. These toxin and the resulting reaction to the body often create nausea. Of course there are lots of other factors at play here including just being emotionally upset about the idea of having to give up foods that you love.
Depression can really intensify during withdrawal.
Even after experiencing clearing and the physical and mental improvements that come with it some folks will have a very strong sense of loss. I understand the connection between the antibiotics and the die-off reaction, but Linda had the antibiotics three months ago. She arrived back from Vancouver on a Sunday, was diagnosed with tonsilitis on Monday and had one dose of antibiotics Monday evening, then three more on Tuesday. Wednesday morning the nausea and constipation hit big time and has never gone away completely. She has eaten reasonably well, but was not close to a perfect whole food diet during that time period.
