Not sure if this is the right spot to put this, but I just wanted to know if the terrible migraine-like headache I had for about five hours last night is normal when you start changing your diet and cutting things like sugar out of your diet?
I usually have a little bit of sugar, but not too much, though yesterday when this happened I hadn't had even a single piece of sugar outside of those in things like fruits in over 5 days. After having a bit of peanut butter (in a satay sauce with dinner and then as a peanut milkshake with greek yoghurt & ice cream instead of just ice cream) I found my headache faded back.
Is this normal, or should I get this checked out or something? It freaked me out a little and I honestly felt dreadful for ages, so... anyone know?
