I am now using the injectable form. I find the initial side effects are worse for 15-60 min following injection, then the head pain subsides, but all other migraine symptoms remain. It is more effective for the pain than a tablet or nasal spray, but mercy the "hit" of side effects (nausea, palpitations, "trippy" feelings, etc) is awful! Is anyone else using this medicine and form? Would you share your experiences? Thank you.
