I used to get headaches , Type 2 diagnosed , HBA1C is 6.4 diet only ...... I had headaches for years . looking on web sites wont help .I was convinced that I had a brain tumor ..... even telling the doctor that I had a brain tumor ,hahahaha ,there are so many things that can give headaches , a simple effective remedy I find is Hydration , drink as much water as you can ......throughout the day this hydrates , vasodilates the vesels and brain ....which is like a sponge . you may be dehydrated by the evening , cos you haven`t had enough water !!!!
Might help you, try it !
Resist the Metmorphin , I am on diet only , yes , its a struggle as you say , but .......YOU CAN DO IT !!!!!
All the best , :thumbup:
