I tried pill splitting to save money. My best splits of a single scored 20mg Adderall tablet yielded "roughly" equal pieces. Perhaps one piece had 9mg and the other 11mg. I had trouble. I was and remain astonished over how sensitive our brains are to this type medication. Most of my splits were not "good." A bad split day resulted in one dose ~6mg and the other ~14 mg. The difference was obvious. The crack didn't follow the score. All splits resulted in some powder loss visible on the splitting surface.
Errors multiply when splitting a double scored pill. The small error from the second split is added to the small error from the first split. The four pieces from a 30mg tablet should be 7.5 mg each. I can see the four pieces ranging between 6 to 9 mg each on a good split.
Talk to your doctor about the problem with a caveat. Many doctors don't think the small differences make any difference. My shrink knew straight up my splits were the pits. He rewrote my script. Problem solved.
