I'm 16 and I've had acne for just over 2 years. I've just been put on Roaccutane 20mg but have to take 2 a day. I only started taking them on Wednesday and today when I woke up I was lightheaded and I've been like this all day and night. Then when I've just been laying in bed my hand started twitching and fingers moved itself. I don't think I've ever had this before and I might be over reacting and it could be nothing but I'm slightly worried as I've been reading reviews on this tablet and what it can do to someone. Has anyone else experienced this side effects and is it normal on day 2 ?
