Insomnia And Muscle Spasm

Hello

For months I have had quite a few problems sleeping well. My brain wakes up after two hours of sleep, and can't switch off after that. At times I can't even fall asleep at night. Even taking an hour nap on a week-end prevents me from sleeping at all at night on that day.

I also have been experiencing muscular spasm on my left arm and shoulder, few hours after my 1hr to 1.5 hr session of exercise, while at rest working on my PC. On one occasion I woke up while the spasm was occuring. This has only happened four times in the last 3 months. The spasm attack lasts for a few hours.

I also at times gets anxiety attacks that affects my blood pressure a lot.

I am on HBP medication as well, but at times my BP goes up whenever I get too anxious.

I am looking at a short term, and long term solution for these disorders of mine.

Is 'Valerian 2500 Plus' a good long term solution ?

What about Diazepam as a short term relief ?

Are there any side-effects of taking both the herb and medication at the same time ?

Any other remedies recommended is welcome.

Thank You :-(
