Well, my OH isn't eating primally but has seen the results of my new WOE - the completely new wardrobe of smaller clothes, the better complexion, more energy and the fact that I stuck to it throughout my back injury rcovery - I would have gone back to CW or eating rubbish before.
My mum has been relatively supportive, since she suffers with a gluten intolerance (not as bad as mine, but still), so she gets it. And as a kid, we always ate lots of red meat and veg, but just with the carbs as well.
I'm not sure if that's helped at all, especially as the issue seems to be the number of meals versus what they consist of. I hope someone else can be a bit more useful!
Hope your heartburn improves. I have realised that drinking black coffee does that to me, so that's going to be very occasional now (I cut it completely at the beginning).
