Ever since I got pregnant I have had almost constant headaches. Get them easily and also suffer from migraines generally anyway, but in this pregnancy it has just become ridiculous. Don't want to keep stuffing myself with Paracetamol all the time, either, and that doesn't really help much anyway. Now I've heard somewhere that if you regularly take Magnesium that can pre-empt headaches. Would like to try this, but don't know if you can take extra Magnesium in addition to the Pregnacare tablets, or if that would be too much? Anyone know about this?
