Only LD after night of drinking/attaining Lucidity

[Gerter]

The only time I seem to LD is after a night of drinking, it is very odd. I think I should start drinking more Anyway the last one I had I was in a big house with my partner and she wasn't happy with me about something. I went outside which caused me to RC, and a random lady appeared and helped me become lucid, it gave me a huge rush of euphoria down my body. I started trying to fly (that's is always the first thing that comes to my head once lucid) But I would only get as high as the house's roof, before I would come down. So I could like fence hop but not get right up into the sky. Is this normal for a beginner LD'er? if so how do I try get further? Also how do you change the setting you are in? i.e in one country and want to be in another.
