You could consider eszoplicone/lunesta, as it seems to be less side effect heavy as ambien (night eating, walking driving, etc.). Etizolam works better IME than lunesta, and is available w/out prescription from oversees pharmacies. I suggest the TOWA brand from a japanese pharmacy. Clonazepam does work very well, but will likely lead to more of a tolerance issue and downregulation of GABA receptors than either lunesta or etizolam. It might also be worth trialing the cycling of different drugs, to prevent building too much of a tolerance to any specific substance. You could consider 1 month of substance A, 1 month of substance B, 1 month substance C, and go back to substance A. Or you could do on a week by week basis.
A time-released melatonin helps me. You'll have to find what dosage works best for you. Right now 3mg time released is working well, but I am going to tone it down to 2mg. Many respond best to doses of the 0.5 - 1mg range. I also feel that 400+mg of a magnesium glycinate helps before bed, and perhaps ginkgo biloba.
Sleep hygiene is important. Bright, natural light in the eyes early and mid-day, and keep blue light to a minimum in the evening and especially before bed. Apps like Flux for phones and PCs can help reduce blue light emission from screens. You could also consider blue light blocking safety glasses (under $10 on amazon). I have found HRV breathing (such the emwave pro from heartmath) to be helpful. You can also just use a breathing timer with an app (I use Pace Breathing) and make both the inhale and exhale set to 5 secs, so that one respiration takes 10 secs, and therefore 6 respiration per minute. Doing this for 15-20 mins when I wake up in the middle of the night really seems to help.
Finally, I am trying a CES machine right now from Fisher Wallace, but it is too early to tell if it is helping at all. I will report back on that once I've had adequate time to test it out.
