I use a Marpac Sound Screen white noise generater to lull me to sleep. It has two volumes, loud and louder. Amazon has them for a little over $50. Well worth it. Pure blissful white noise!

Taking Amitriptyline has been great for my headaches but as a side effect it gives me bad acid reflux. I take a dose an hour before bed so the heartburn I get results in insomnia. I try to take my dose with a good natural antacid like a banana. But if I'm out of bananas, I have to try and sleep in an inclined propped up position so my digestive tract isn't strained. It's pretty hard to get a good night sleeping in this position, even with the white noise. Often I'll go in and out of sleep throughout the night. Sleep for a few hours, wake up for several minutes, then back to sleep repeating the cycle.

I can tell what little sleep I may get is good quality REM sleep because I always have very vivid dreams. Sometimes in my dreams I'm in there recalling other dreams. Dreams within dreams...Freaking weird! I wake up in the morning thinking, "Wow, the Amitripyline packs a punch!"
