A. My doctor says the help to add endorphins in the brain and it balances out your feel good mood. I can tell you that the right medication can really make a difference so don't give up.

Q. I was taking Lustral and I suddenly stopped it for no reason. I was taking Lustral and I suddenly stopped it for no reason. I could only sleep for an average of 6 hours a night and then wake up, and recently I've had spells of cry and I am scared of my future. My sleeping pattern affected to a great extent and now a days I sleep rarely for about 3 hours. I don’t know where it is getting me … what I should do…..

A. I think you have stopped your medicine and the control on the disorder is lost….so please start taking your medicines again but before meet your doc and explain the difficulties that you have experienced . It’s a risky attempt to stop on medicines which is your lifeline. Don’t ever stop medications unless and otherwise prescribed by the doctor to do so. It is my sincere advice to you.
