I took Aciphex for 1 day and at bedtime I had a hard time falling asleep as my heart kept "leaping" and I'd literally jolt when this happened through the night. Also, got what seemed like a bad migraine head (I usually don't get many headaches at all) for many hours. I'm not sure to try another pill even for the 2nd day after coming upon this ominous but true website. It did seem to relieve some abdominal pain on my left side I'd been having for weeks. I'll have be wise and pray about it.
