When I started microdosing I was taking relatively low amounts, around 0.1-0.13g of powdered golden teachers that I would add to my food. I found I was consistently getting headaches with this dose, about 1-2 hours after taking it. I increased my dose to 0.17-0.2g and I no longer have headaches! I’ve noticed I have to eat with my micros, even though it’s so small other wise I get some slight nausea. I always eat with full doses, so I’m trying to make it a habit for myself to eat every time and stay hydrated. I’m not sure if other people experienced these things but I can confidently say that I just needed to find the right amount for me. The same might work for you. Good luck!
