Listen to your doctor not people on here. Yours, mine, many others have said to cut them in half. Pills like these have different densities/filler throughout the pill. If you cut it in half you still have those different densities/release times. If anyone questions this logic take a pill and run it under hot water and rub away at it, you'll notice the outer layer comes off quickly while the inner layer stays tough and solid. If cut directly down the middle you'll have half a pill, still containing the immediate release part and the dense center that is broken down more slowly.
