I was doing sip breathing for about two weeks, hour per day. About 4 days ago i started to have a serious problem with sleeping, for ex earlier I sleept for about 9 hours, now i sleep 4-5 hours and with problems, I awake few times during night. After this three nights I feel quite tired but i still cant sleep normal. Cause of this I stopped sip breathing. What do you think about this, is this normal and passing problem
