Yes you can,
I was getting migraines when I first started detoxing - for me it was a case of too much for my body at first. That period of time, where detoxing 'set off' a migraine, didn't last long though for me. I still get migraines, just not from trying to detox.
In my opinion though, that would be different from a 'toxic headache' is when I actually feel toxic & have a weird headache - it's really hard for me to describe the headache itself though.
Blessed are we who can laugh at ourselves, for we will never cease to be amused!!!! :)
May we all find peace along the journey to find healing.
