Thanks so much for all the advice yesterday and today. I think the water comments may be on the mark. Like Julianna I always drink A LOT of water - at least 2 litres a day - so that may be why I didn't have symptoms until now. But yesterday I was trying not to drink water out of plastic bottles (because of the freakout about the endo) and the glass bottle I found was only 0.5l, and I didn't get the chance to refill it much, so I must have drunk closer to 1.5l, which clearly wasn't enough. I drank a lot when I woke up at 5am this morning, kept drinking through my horrible nausea in the morning, and by lunchtime I was actually sort of ok.
I've been chugging down the water ever since, and note that every time I slow down my head starts to feel like my brain is just scratching against the inner surface of my skull, so I start drinking more again. How this is going to work when I'm leading a workshop tomorrow, I don't know, but I'm sure it's better than throwing up on everyone, so I think I'll give it a go.
I'm also trying to follow this diet regimen, but realised at dinner tonight (at a hotel) that I'm ending up inadvertently doing Atkins, only worse (no butter and cheese etc), because no carbs I get access to outside the house are legal. I'm very anti faddishness in general, which is one of the reasons I haven't started lots of other remedies and dietary changes earlier, and now here I am sort of following the ultimately faddy diet. Damn. Got to find an alternative. I'm feeling constantly antsy about trying to do this because it seems so faddy. I wish there was some proof it worked because maybe then I wouldn't be so self conscious. It did, however, stop me from eating the lovely looking cookies that were at the business centre desk this evening. I thought nothing would replace the motivation I got from 'fear of the big white dress', but maybe I've found it.
