Hello, I have previously found two American studies on the drug and how it effects people with brain damage. I deleted the info I collected after not being able to act on the problems at the time, but after 2 and a half years of being off the drug I am still a chronic insomniac. Ive spent a couple of hours searching today and havnt been able to find Uni studies which contain this information. Can some one give me tips on the best way to find the info im after?
