In case this knowledge can come in use for others: AFAIK it's the chitin in the mushroom which causes nausea and discomfort. I've read about eating ginger root before ingesting the mushroom to reduce this. Although I have not tried it myself.
Another good way of ingesting the psilocybin is to make tea from the mushroom. This reduces discomfort for those who get unwell from eating it. For some types, such as psilocybe cubensis, it's recommended to squirt a bit of lemon juice in the mix. This will supposedly help extract the psilocybin from the mushroom.
As for potency, it's recommended to use a mortar and pestle to pulverize the dried mushroom into a fine powder. Potency should me more predictable and consistent after this.
