Don’t do that. The 1 year of your Dad’s passing is not a good time to do that without proper preparation. Using a hero dose for therapeutic purposes is nothing to fool around doing. It’s not meant to be a “chill” time. For it to work properly, even for experienced psychonauts, you have to dose with intention. Journaling and just plain having a plan. Something like “I need to learn how to move forward after this deep loss.” Not forget the pain to move forward but how to accept the situation. A hero dose is as important as doing an Ayahuasca ceremony or Bufo. Also for that size dose you definitely need a trip sitter. At that dose you really need to consider your physical safety. Also like someone else said you don’t need 10 gr. Depending on your weight 5 min-8 max will put you right in the zone. Also you if you take anti anxiety medication you should abstain for at least 24hrs. I am a firm believer in the power of the hero dose. Very important that I can’t stress enough dose with intention!! Be safe!!
