I have been practicing Suryanamaskar for about a year now. i do about 10 every morning or evening close to 4 times a week. Recently i started doing super brain yoga (about 20) every morning, for 3 months now. I have had insomnia for close to 3 months and am not able to figure out the cause. I went to the doctor who has ordered a sleep therapy, but could not figure out any reasons as of now. i sleep at 10:30 -11 pm and wake up after 4 hours. Then my sleep is disturbed with lots of dreams (normal dreams). Right now I am using melatonin and have decided to stop yoga practice for a month. Can super brain yoga lead to insomnia or higher activity in the brain. I have heard about kundalini awakening, but I dont meditate and am too young for that. However after super brain yoga, i have some tingling sensation in my head. Like it is flushed. I would appreciate if anyone could throw light on this subject, if any. Thanks.
