Dear All,
It's always nice to get back here with some update. Here it is.
In the last two years symptoms gradually faded away 100%. In the last few months I had reached NIRVANA :D , being able to sleep without any issue. I am praciticing a lot of Kundalini Yoga since March. One month ago i even quit smoking marijuana (i used to smoke a very small joint everyday before going to sleep).
I am also reducing alcohol a lot, because it conflicts with my yoga aims. It unbalances all the work done with my classes.
During yoga i often feel pleasant healing shivers going up through my spine and behind my neck.
On friday i went to the beach and played beach volley after a long break....then went out for dinner and i drank wine (1 litre more or less, but in 4 hours), and could sleep normally that night.
Yesterday and the day before yesterday, I went to a lake with a friend of mine, did not take any drugs nor alcohol, and played volleyball again. Before going to sleep I was playing around with facebook and stuff, as I often do.
There was also a party starting at the lake, and they even offered me some MDMA. I immediately replied that i can't anymore, but that if i did not have this experience, i would have taken a little, and that i was very sad that, because of my mistake, now i can't have any.
This friend of mine was quite annoying and attacking me a lot. In the past i would tell him to fuck off immediately, but now with yoga i've learned to avoid negative thoughts and decided to just let it go.
In the last two days, surprisingly enough, i had those tics coming back. I think i realized (i may also have mentioned before) that for some reasons while falling asleep, my breath stops, and it is like if my brain gives me a zap to remember me to breath again.
The day before yesterday, after 2 hours of tics and twitches, i got up, had a camomilla tea, watched tv one hour until i felt sleepy again, then went to bed and fell asleep quite easily.
Last night this trick did not help either. I had other 1-2 hours of tics. Then i fell asleep at around 4.
I am quite worried again now because i did not overdo anything. I did not eat any different food than usual.
The only thing i've added in my daily activities was volleyball, but i don't understand how that could cause my symptoms to re-occur.
Or maybe just thinking about that party and the MDMA was the cause ?

It seems a bit exaggerated.
Maybe, as reasonably mentioned by FBC and Panos some posts before, it might be related to anger, in the sense that I repressed my reactions towards this friend of mine and did not tell him anything ? If this is the case i should find a way of reacting that would not conflict with my yoga principles.
I will try to think better about the possible causes and would be glad to have also your point of view or any comment.
I will not play volleyball anymore and will see what happens.
Today the back part of my neck is quite stiff and unpleasant.
I hope it was just these 2 days and tonight i will sleep normally but will keep you updated.
Cheers all
EDIT: in the afternoon i could not sleep becuase of tics. I was thinking it can be something physical. I remember i had the same problem with swimming butterfly, bending my neck backwards seemed to squeeze some point that would cause the symptoms to get worse. Maybe i did the same jumping and rolling when defending and receiving playing volleyball.
EDIT 2: so yesterday i had a relaxing day, just stayed home, also because i was tired. At 10Pm, before going to sleep I had a camomilla tea. On the sofa sometimes i felt muscles on my arms twitching a little so i think the volleyball left some tension in my muscles, since i did not play for a long time.
At 10:30 I went to bed. I had maybe a couple of very small tics, but not real "jumps" as the previous days...in fact i could sleep well afterwards. I went to bed with the state of mind that if it happened again i would try to ignore it, without changing positions one hundred times as usual.
So i think it definitely has something to do with the mood and state of mind. But there might be some physical aspect that triggers it, at least in my case.
I hope it was just temporary as i suspected.
