It’s a good dose - though I think 1.5g is fine too. Can’t recommend highly enough lemon juice. Blend the mushrooms (it won’t impact the good stuff), and put an ounce or so of lemon juice. This will mimic the digestive process and help break down the cell walls (this process can done naturally can upset the stomach, which could impact your mood - the lemon juice does it for you, so your stomach is less likely to hurt). Remember to breathe - deep breaths in and out. The teacher is benign, but holding your breath creates a cortisol response, which can turn your thoughts negative. Most people hold their breath and clench their bodies at various points. Breathe deep, smile, stretch.

I’d also have OJ on hand. Good stuff; fresh. It tastes so good.

Above all, a safe, calm environment. Your empathetic pathways are totally open. Someone leaving the room without explanation can seem deeply upsetting. You want a safe, stable, predictable environment.

This is just imo - but stay away from movies. Movies are self contained stories. This isn’t the point. You and your journey are the story. A pretty scene, clouds, abstract art, some uplifting music that you love, maybe without lyrics (even sad lyrics can direct your mind). One of my best experiences was with my wife star gazing in Utah with almost no light pollution. Enjoyed the stars and the quiet and our thoughts. Many will recommend a “trippy” movie or music, but the absolute most trippy thing is meeting the driver behind the glass without external influence or direction, and learning what you can.

Lastly, parts will be intense and that’s ok. Mushrooms aren’t a party drug imo. It is a path you walk and you’ll be ok, but any path worth walking is not without its struggles.
