Yes u can, but...: You can use omega-3 supplements, but I am not sure if it is going to help you much at all. Based on your symptoms, it is possible that you have attention-deficit disorder, especially if this has been since you were a little kid, and getting an evaluation by your doc is advisable. Omega-3 is relatively safe in moderate amount, but there is no evidence of help in this area...Good luck.
