Hello,
this might seem little bit silly, but im looking for any realiable techniques how to wake up from lucid dream. I know that usually people want to stay longer and not to end it, but sometimes when it is too long is there any realiable way to end it?

When I was experiencing with supplements i had some long lucid dreams lasting about hour and wanted to wake up. At that time it was pretty scery and I started panicking. What I did was pinching my skin or hitting my body to something, but that only make the dream more vivid and stable, because it is basic stabilization technique.
