First, if you take a benzo, you have to stop the valerian -- they both target the same neurotransmitter (now, if you really know your herbs, if you take the valerian far apart in time from the time you take your benzo, you can do it, but nobody not very well educated about herbs should take valerian and a benzo. Second, when do you take your magnesium? Benzos and antidepressants and other drugs that target brain neurotransmitters use the magnesium pathway to get past the blood/brain barrier. If you take your magnesium at the same time as you take your med, only one is going to get where it's trying to go. This is why so many people who take antidepressants get muscle pain and problems with digestion -- they're often interfering with the absorption of magnesium. Third, you're on a lot of drugs with so many possible contraindications, including ones nobody has discovered yet, that for you it might be a problem. This is a problem for anyone who takes a lot of medication. Fourth, gabapentin, is GABA, it's not like GABA (though of course it is synthetic). It's formulated to go straight to your brain so it completely bypasses the digestive system, which probably avoids the magnesium problem. But it might have burned out your GABA receptors -- it's the reason so many people who take this drug have to keep upping the dose and then it taps out. Can't say this happens, but it's possible. Now, none of these could be happening -- it might be your liver metabolites or some other protective agent in your body just don't like benzos. It happens. But there are a lot of benzos out there to try. You might be looking for more from them than they can deliver given how many drugs you've been on, nor are they sleep aids -- they interfere with REM sleep and any drug taken for insomnia will eventually cause rebound insomnia. The only cure for it is to get rid of the cause of it, which I admit is really really hard to do. If you really just can't sleep with the help of melatonin or exercise or meditation or lifestyle changes or natural remedies, take a sleeping pill, not a benzo. I wonder if you had your blood checked to see if the benzos you took were successfully building up in your system? One other idea -- taurine, a pseudo-amino acid, along with B6 is what the body uses to make GABA. Taking GABA as a supplement generally doesn't work, because it usually doesn't successfully cross the blood/brain barrier. That's one of the reasons neurontin and Lyrica became so popular. But you might find benefit, as long as you're not on a benzo, from taking some taurine along with your valerian or, better, kava or passionflower, and see if it helps. You obviously have a pretty severe problem so I don't know how much this will help, but since you're taking this stuff and it isn't working, it's worth a try. Most times combining relaxants works better than taking one alone -- valerian works better taken with hops and passionflower, for example, than by itself. But with kava, because you're on so much medication, a few people reported liver problems with it, so make sure if you try it you're other meds don't present that problem and you don't use the standardized version of it. I found kava to be the closest thing in nature to a benzo. Good luck.
