Tea would work, but its very hard to pull it off right, and very easy to mess up. heat is the number 1 enemy of potency, when it comes to mushrooms.
another way that helps, is to avoid tasting them. also the more you try them, and taste them the more your body "associates" the flavor, with "sickness" and your bodys natural defence macinisims will make u nauseous, and want to puke to save you from yourself, and becoming sick. So the less you taste them, the better in the long run.
Ok with that said. let me list some of the ways that might help you. first is disguising the flavor. Peanut Butter, is a godsend! crunchy, even better. the easy way, take a big spoon of peanut butter, and press your mushies into it, and eat. My favorite way, is get a cheap $12 coffee grinder, grind your dose into powder, and then take 2 peices of bread, with peanut butter on both breads, and sprinkle the powder on both breads, and slap them together. you wont taste a thing!
You could also try peanut butter balls, get s big spoonfull of peanut butter, and slap it onto some wax papper, add crushed gram crackers, and your dose to it, and mix. then add powdered sugar, and roll into a ball. then if u want u can roll in nuts, or chocolate chips! stick them in the freazer for 45 min. and eat! they will keep in the fridge pretty well for a week or two in a tupper container. =)
ive tried the mushroom chocolate methods a few times, but in my opinion, melted chocolate is a pain in the ass to work with. never turned out quite right.
something i would like to try but havent had the chance yet, is mushie jello shots. just swallow down the jello, and your done!
other advice, always try to start with as empty a stomach as possible, try to skip the meal before you trip. you wont be hungry once your tripping.
also, u could try pepto-bismal, or ive also heard good things about ginger or pepermint tea to ease your stomach. (look for stomach teas in the tea section of you grocery store)
Or ive even heard smoking weed after taking them helps. but never tried that eaither.
I took Shrooms for the first time yesterday morning, just 2 grams. The experience was amazing, but the nausea was annoying. When the trip first started it was intense visual distortion wise. I remember sitting in the bathroom expecting to throw up seeing the parts of the floor raising like people were trying to punch through it, things were moving, etc. But by the time and hour had passed the nausea had gone, along with the intense visuals, and instead it was replaced by deep feelings, pure peace, and bright vivid surroundings. (expecially outside). I think I had a 'level 2' trip (by Shroomery standards). I was going for a' level 3' trip.
