I have a problem with insomnia as well Atkeni. While visiting my friend over the holidays he let me try some White Rose he had recently grown. I don't think I've ever found a strain that helps quell the insomnia better for me. The best part was that it gave me a pleasant stone that made me feel drowsy but still able to function if need be. It might be a strain you'd be interested in trying as it is supposedly 100% indica. He said he ordered the seeds from the Rhinoseeds company. A quick google search should give you a link to their site. I hope this information was helpful.
