I have had a TBI & the consequences have been devastating. As you all know, we are the group of people who really NEED meds to get a full nights rest!
Personally, here are my results:
Ambien 10mg: works good for me thus far (thank you God), and it's been working for a good month or two.
Lunesta 5mg: works good but waking up is morbid, unadulterated torture. I sleep FOREVER on that stuff! YES, I SLEEP FINE ... but waking up is not good.
You may have different results. I know that some people with a TBI have great results from Lunesta.
I certain of this: Each person is different & you've gotta have a doc that will be okay with letting you try just about everything. I assure you ... don't give up because your med is out there!
