Why is my stomach doing flips all the time? I have fibromyalgia, acid reflux, and ectopic heartbeats the omeprazole used to stop this but not now.

Many causes. Signals in the heart usually comes from the sino-atrial node but ectopic beats maybe coming from the atria or ventricles cause by alcohol,anxiety, stress, caffeine, tiredness, smoking, pregnancy, recreational drugs, cold medicines, or menopause. See your doctor to reevaluate your treatment for acid reflux as well.
