Healthy way to cure my insomniac

I always had sleeping problem since college, and I depended on Tylenol's sleeping pills for approximately 7 years. As a result, I couldn't fall in sleep without taking a sleeping pill no matter how tired I was .On the past Tuesday, Ms. Tomato took me to this health class some kind of thing. I learned that sleeping pills will damage my brain cells. I also learned that if I take 4 caps of Calcium and 1 cap of B complex, I will be able to adjust my sleeping problem. So it started to take them on Wednesday morning. The result is showing on the 2nd day. This thing works exactly like sleeping pills except it's healthy for my body. In regards of the sleeping quality, I ain't able to wake up at nights by little noises like before.
