It's OK to take a break for a night, or for as long as you need. But I would not go method-hopping. Pick one a and stick with it. Otherwise you will not know if it works had you tried for little longer.

Here is a basic MILD tutorial. Please check it out and see, if there is anything you could be doing differently. MILD is a powerful method, but if you added some awareness to it, you would have a better chance of a LD.

So check out the DILD while you at it.

If you trying too hard, it may not work. Maybe that's why some people report having LD the day they stop trying. You really should not be wanting it or trying, you should be more like "I know I'm having LD tonight".

Wishing is just that - hoping that sometimes in the future you will get lucid. But Knowing - that's setting your intent. Just as you set your intent that you will go to school/work in the morning. You don't wish to do so, you know, that it will happen.
