Sorry for my English and thank you.

No worries, many of us here are bilingual. English isn't my first language anyway.
Ok, so here are my thoughts:

I just can be able to partially project 3-4 times while I was in the army. It was april 2010 - september 2010. But I couldn't be able to project after that when I've returned home. It's possible that the exhaustion and homesickness combined with the tension of wartime combined to give you a state for projecting. You came home, you relaxed, and one motivation went away. So let's see how to change your conditions to make them better for projection.
I'm meditating every night before sleep since 2 years. It's time to change that. When you go to bed at night it should be to sleep- you have trained yourself all your life to go to bed and sleep- now you're telling your brain to do something else, and this is confusing. Some people take to this, some others don't.
Try getting up one to two hours (depending on what your work and life schedule is) before waking up and then trying to project. Not every day, every three or four days or so- if you have a busy life, do it on the weekends only.
This will train your mind to project at it's own "special" time, not at a time when you expect to be sleeping.
If this is not too much, find from fifteen minutes to an hour to do your meditation. At this time you are not going to try to project, you are going to meditate to trance, observe what you see and then come back to waking. Consider this 'taking a tour of your mind', and this is the time you make adjustments to your sequence- add things or remove them according to how you've changed.

I'm trying to be lucid while dreaming, which usually doesn't work cos I'm still not using a dream journal. If journaling is too much for you, do keyword writing. When you wake up write three words related to the dream that's still on your mind, and then later read it again and see what you remember. Use affirmations at bedtime, such as "I remember my projections", or "I know when I dream", and do reality checks. These are easy, and you don't have to do them all the time, just for a few days.
I even can't get any symptoms either. Symptoms come and go and change, that's why I want you to meditate to observe your mind, and see what you can learn from this.
Things like projection and dreamstate lessons are evolutionary- that is, they change and cause you to change, and transitioning to private life is a big change that has required some adaptation- so it's possible that it was not to your advantage to have nonphysical experiences as you were adapting to your everyday life. But if you feel you're settled into a new routine, I would advise you to start a new one in the nonphysical department also, with the changes I outlined for you.
Good luck Corey.
