Can you give me a site (or do you have one) which shows which pills are physically scored so they can be broken in half?

Here you go : Pill Images - Drug Library - DrugDigest (http://www.drugdigest.org/DD/PillImages/PillImagesSearch/1,20327,,00.html)

Just type in the name of a pill and it will give you pictures.

Here is an example of one.

**EDIT** - For some reason the link above didn't show up as it should, but just copy and paste it into your browser. :)

This should be able to help you too : Drugs.com | Prescription Drug Information, Side Effects & Interactions (http://www.drugs.com/)
