@stone34 It has been 7 months since I've been dealing with insomnia. Spoke with my internist today and he said, "You must sleep." Then explained how insomnia complicates all processes of the body. Believing my other MD who put me on a medication and said "take it daily nd in 6 months you'll be sleeping." It's been 6 months and I'm sleeping at least one night a week for 12 hours and other days I sleep 6-8 hours. It takes a long while for the meds to build up in our bodies and then it takes effect. I trusted my MD and it worked. I must be careful to regulate the temp of the sleep environment as that will interrupt sleep very quickly! Hope you get sleep soon. Only you can decide if you need to retire. Taking a leave to evaluate your needs sounds reasonable. Good luck. Truzie

Have you tried a sleep clinic? A lot of teaching hospitals are into this issue recently, they would probably love to get you in a program b/c of the PD complications.

Also, you might want to consider changing your internist ? A second opinion perhaps? (Use a different practice if you do this).

good luck, I am now on my way to bed to toss around until 3 - 4 am

I was having so much confusion at my job, memory lapses, panic attacks, crying jags--I confided in a colleague who recommended I talk to a disability lawyer. So very glad I did --in 4 months I was approved for disability. A tremendous relief

I retired due to this sympton and others.

Lack of sleep is disasterous for PD symptoms. Here's a recent review article about why and how to fix it in a leading journal:
