I always make a tea, it has never made me feel very nauseous. There's a little discomfort here and there, but only if I pay too much attention to it. Tea also will extract psychoactive compounds while destroying any toxins in the mushroom.

Assuming you take them dried, try this:

Bring water to a boil (10 fl/oz per dose), then turn the stove down and let it go back to barely a simmer. You don't want to boil them, but you want it to be pretty close to the boiling point.

Grind up your shroomies nice and fine and put them in a reusable tea bag. Drop the tea bag in the water for about 10 minutes (leave it on the stove at like med-high heat).

Then, take the teabag out, and pour your shroomie tea into a cup and let it cool before you sip. I never bother eating the mash that's left in the teabag, it all gets out into the water just fine, but you can just turn the bag inside out and eat what's in there.

Add some lime or lemon juice to the tea if you're still worried about nausea.

I know this doesn't directly answer your question, but you can eat or not with tea, doesn't really matter much. I drank mine after a big ol dish of tortellini
