How much is too much when it comes to sleeping pills?

I have horrible insomnia. I will lay in bed for hours at night only to fall asleep around 5 or 6 and getting up at 8 because I have a toddler. at first my Dr gave me ambien and I hallucinated, called family members, and slept walked and then felt horrible the next day! so then the Dr tried tradazone. sometimes it works sometimes it doesn't and I almost always forget things that happened the night before. so then I tried alteril natural otc and that didn't work. as of now I take 100mgs of unisom otc. it helps me fall asleep but I can't stay asleep. I feel like a zombie during the day. does anyone have any suggestions to something that will work and not make me groggy or feel loopy? I've tried everything from lavender, meditation, sleep aids, even massages from my husband. I'm so tired of being tired all day! I'm drained
