Welcome to the Nexus, whippa craka!
Looks like a wonderful first extraction! Sorry to hear that you're feeling ill, but I doubt that it's related to the extraction process at all. SWIM's accidentally gotten a pretty full load of solvent before, but after a couple of hours the headache went away and everything was fine.
As for first time advice, maybe try out a rue extraction to go along with your spice journeys?
Be well.
