Hi loves, mine happen naturally and I also make them happen and it's right that sometimes when it's really emotional it can wear you out emotionally. I have never been physically worn out though, you do get the same rest physically as you would if it was a non lucid dream so don't be put off in any way thinking it will tire you out. Good luck and glad to hear you have someone you can speak face to face with, I don't but I have all my friends here on DV and for me, that's all I need.
