Hi! it didn’t give me headaches, but in the beginning it was Really hard for me (especially the first 3 days). I felt like I’m getting rid of addictions. After a week passed with no sugar (I was cutting artificial sugars. During this time I was eating fruits, which has natural sugars and is very different from artificial. It also process differently) The result was extremely good, more energy, more happiness, more focus, easier to work out 👍👍👍👍. I wish you all the best 😊👍
Btw sorry for my late reply.
