I feel sedated a bit and want to know how long should I take as little as possible to feel normal and not sedated anymore.

 I don't want to really develop any dependency.   So is it better to take as needed? But then if I do that I don't think I ever get a steady state and get sedated when I take it so I'm not sure if it's best to take as needed or on a regular schedule to keep anxiety under control.

Sometimes I take it at night and do not feel like I need it in the am as much as it helps me sleep better too.  TIA
