I just weaned myself off risperdal and lamictal and I have terrible insomnia. Maybe it's just coincidental because I'm 51 and probably perimenopausal but it is impossible for me to get a good night's sleep without Ambien. It takes 1 1/2 hours to fall asleep and I toss and turn all night. I was diagnosed last summer with bipolar type II and I began to doubt the diagnosis and I realized that my psych had me overmedicated...there was literally no animation in my face so I gradually (over six weeks got off the meds.) I also believe that I don't suffer from BP and PTST but a sleep disorder. Even though I have serious insomnia, I'm staying in bed for 8 to 9 hours and probably getting more than the 4-6 I was getting at the time of my diagnosis.
