The resintk by house will yield some nice full spectrum product.
Otherwise, you can use the 69ron tek using CaOH to get some mescaline salt.
Or the Plux- tea-tek...
I have not suffered nausea from mescaline or resin. Though i recommend not eating too much resin at once, since it can be hard on the digestive system. I had some minor cramps after eating some grams all at once.
I dont know about your tea ("created using mjshroomer's guide" )... But i dont expect it to be nauseating because the whole cactus was used. House's resin tek states not to mash the cactus because mashing it up will make it slimy/gooey. Without the slime, the volume of resin will be smaller. Which is a good thing when consuming.
