Wash them in a collander with warm water and a mild soap , if you still get sick try taking 1 tablet of dramamine .
extract the polar stuff (LSA) and leave the nonpolar stuff (puky nousea crap) in the seed mush. easiest way to do it: use cold distilled water over ground seeds for ten minutes and then filter. polar stuff goes in water, nonpolar stays in seed mush.
ive found that dramamine taken about 30 minutes to an hour before seeds help alot,also have pepto handy
Just "bite the bullet" and get throught it...it will be well worth the nausea when the trip starts kickin in.
I just grind them up and then dump them in a blender with 8oz of skim milk. Haven't thrown up yet. I felt a little nausea with a high dosage but didn't throw up.
Pack the powder into 00 gel caps, that way you dont taste a thing... and if the nausea still bothers you, just smoke a little grass.
