Hi, hope you can help me with my brother, i guess his suffering abnormality due to stress or what- can you advice me some medicine to calm him down? he had a child history of being blue baby when my mom gave birth to him. But he has a normal look but slow thinking but he act so well he can read and write, he's 30 years now, This past month he's acting so strange, he's always hyper, he can't stay to long in our hours doing nothing, he doesn't sleep lately, he always smoke cigarette which he's not doing when he's in normal condition :( He always woke up 4am but that's not he's doings before, i guess he sleeping 4-h hours a day only.
