I'm a 51 year old male with PD. I know that insomnia is a common sympton, and I've been taking ambien to help combat that. Lately however, the ambien is not keeping up it's end of the bargain. I'm lucky if I can catch 4 hours of shut-eye and it's getting frustrating! I find myself losing focus during the day and a little impatient (if not outright moody).
Are there any meds that I should ask my Dr about?

Ask your neuro about lorazepam.I find that .5 mg at bedtime does the trick.I also use it when stress gets high.It is addictive but then so is pd and pd meds.You gotta find something that gives you more then 4 hrs sleep.i was dx pd in 98,and currently on stalevo,and mirapex.I find that if I can get enough sleep my stress level is lower,and my meds more effective.Wish you the best.
