Blimey, not sure if I am detoxing or what but my head feels like it is about to explode! Is this commonplace ? I am drinking lots of water and have replaced a couple of cups of coffee with peppermint tea so I may be a bit lacking in caffeine

Yes, it most certainly is common on a diet like this one. Not only are you detoxing from caffeine and other chemicals but also sugar itself. Lots of us have gone through this and you should start to feel better in a day, maybe two. Take some painkillers and keep drinking the water. You will come out the other side feeling a lot better for it.

Absolutely common. Caffeine tends to worsen it (in my experience). I find that taking a sinus pill (I use Advil Sinus) works for me.

Well, it at least takes the edge off of it.

Stick with it. This too shall pass.

Cheers,
