I thought I'd just plug tdcs for sleep. You can find different kits available for $50-$150 online. For me, nothing else has really worked. I was a chronic insomniac but this really works! I put the positive terminal on the left temple and the negative on the right temple for about 20 minutes at night. You don't need to do it every night forever. After a few weeks you simply won't need to use it as much. Not being able to sleep sucks so I thought I'd just throw this out there.
