I took my vitamins two hours after dinner and woke up sick!

Hi, I took my multi, potassium, and calcium vitamins two hours after dinner last night and woke up at 1 AM with intense stomach pain and dry heaves. I am ok today, my stomach is tender and I am eating soft food. I am worried about taking today's vitamins though.
