I too, use Alka-seltzer. I get the “Gold” one. It doesn't contain any aspirin and is potassium bicarbonate instead of sodium bicarbonate. It works well on migraine with nausea and ones that have an intense pounding feeling.
Alka Seltzer works for me if I catch the migraine early.
Anitha, thank you. You are the only person I have known to confirm my experience. The very first migraine I ever had was unbearable. I couldn't sleep, and was throwing up. My husband came home, and brought me an Alka Seltzer original, in a glass of water. It gave me total and complete relief. No headache, no upset stomach, and I could sleep. My migraines have lessened in severity, over time, however. So my other favorite remedies for migraine are 1) a glass of whole milk with a chocolate bar, and 2) a pinch of cayenne pepper on the tip of my tongue for 30 seconds, followed by a glass of water.
