Thank you all for the hugs and support. I stayed off the computer today because I just needed a break from researching things. You know how it goes...one thing leads to another which leads to another. I should have an honorary medical degree by now. 
Susie and BBK - talk to your doctor (BBK, have your mom talk to her doctor) about taking cod liver oil to get the vitamin D - maybe that won't cause the stomach upset. It's high in vitamin D, however I did see a blip about possible Vitamin A toxicity with it which is why I say talk to your doctor before trying it. Vitamin D that is prescribed is D2 and what is in cod liver oil is D3 and is natural. It's supposed to be very effective. I didn't really read that 'blip', but saw the mention of it.
