q21q21, this is from another forum from a guy who took the same dose you did:

That's how it should feel. It should be stimulating, not sedating. Elemicin is not a sedative. The only potent sedative present is myrcene, and it can cause headaches, upset stomach, and other side effects like you felt. If it’s sedating, somehow the myrcene made it through the extraction. If this happens, you might want to add more water to the DMSO before using it to extract the oil. If your DMSO is pure DMSO and not 30% water, then myrcene will make it into the DMSO.
