I have what I would characterize as the typical sleep disorder associated with CFS - difficulty falling asleep, wired but tired, and up and down all night long. I was on Ambien for two years before I quit because of side effects and the inherent risk in long term use. After being off sleep meds for a number of months, I decided to try marijuana as a sleep aid. I don't enjoy the feeling of being under its influence, but as a sleep aid I am finding it tremendously effective. I take just a couple of hits right before I am ready to go to sleep (I use a vaporizor). I then easily drift off to sleep, and most nights, stay asleep uninterrupted for about 5-6 hours, followed by interrupted sleep for another 2-3 hours. Sometimes sleep quality is better than others, but I am astounded by how well it works for me. I have only had one or two nights of poor sleep in months. It has even been more effective than Ambien, and I experience no adverse side effects. I believe that marijuana has anti inflammatory properties. I suspect that these properties help reduce problems in our CFS brains. Or perhaps there are other mechanisms at work. I am having such success that I wanted to share this with the group, particularly since it has become much more widely and legally available recently. Marijuana may not be for everyone, but if you have access to it, it may be worth a try. I'd be curious if others have had success with it, and if anyone has tried a low thc variety. Cheers!
