I'm Currently Taking 100 Mg Seroquel For Sleep Insomnia. After

I'm currently taking 100 mg Seroquel for sleep insomnia. after a couple of nights of taking it, I start having anxiety, So the Dr has me take Buspar for the anxiety which doesn't help. The Dr won't prescribe any sleep meds because I'm on 5 mg oxycodone for a tear in my left hip. I have been dealing with insomnia for the last 2 years. One Dr. I was seeing had me take clonipine and it helped. However, he moved. Last year I even went to Urgent Care for insomnia and they gave me 3, 5 mg of Ambien and I slept great! I'm also starting to experience pain in my kidneys. Can't be good? Thanks
