For a few weeks now, when I've been waking up, I have woken up with tremors. I've been really stressed lately but it started before my stress. I also have a congenital heart disease but I've never had any problems like this before. As of late, I've also been having trouble sleeping, not being able to get to sleep til at least 1. But I've still been sleeping at least eight hours. I've always had trouble sleeping, so should I see a doctor about it? Other info: I'm 17 and even as a baby accorrding to my mom I have had trouble sleeping but it has just gotten worse. I've also had more trouble with my hand having small tremors. And I drink at least a soda a day as far as caffine goes and that's it and usually not anywhere near bedtime.
