Each and every psychedelic experience can be totally different, not directly even related to the amount you take. Set and setting, and your mindset and preparation, the intention that you take while you do it matter a lot. Eating 2g of dried mushrooms can be a life changing experience, or just a fun evening wondering on about the world. It can even not work at all, or give you just a slight feeling of being in an altered state. Personally, after experiencing mushrooms and other psychedelics over a 10 year period of time, these days even a small under 1g dose can bring a very strong experience. Depends a lot also what you have eaten before the experience, how you have prepared for it etc etc .. maybe the headache is something that the mushrooms just brought to the surface in that moment, might not happen on your second time.
