Thanks for the info. It's not a full on nauseous or full on hunger pain, it is a mix. I have tried taking at different times or not taken them for 2 days, just to see. Same results. The noises are fine, but it's the constant dull, achy pain that's making me nuts. I will look into meclizine.

You really need to seek out some medical advice about this.
Generally rumbling, gurgling, etc. is common. Mine can be very loud so I quizzed my surgeon’s partner at a recent check up & she said it was my body doing what it’s supposed to: digest food. (My young nieces & nephews think my noisy tummy is hilarious.)
Pain & nausea is not common & needs to be explored to see what’s going on. The nausea could be the vitamins but that usually only occurs after you take them & doesn't continue all day long. You may need an ultrasound & endoscopy to see what’s happening.
Work at increasing your fluid intake. At 32oz you’re only getting half of what your body needs. If your active or live in a hot climate you’ll need more. You could be borderline dehydrated which could also be contributing to your nausea & discomfort.
All the best.
