I don't know why either, I just saw my meds unopened bottles and said I've got to start taking my meds. My co-worker stated the other day that she really feels good, after only one week of risperdal, she even looks better. Seeing the difference in her hopefully will motivate me. It's like I don't want to wait for the meds to become effective. I have no problem taking my vitamins every day. Just take them
