hi..thanks for writing...i have understood your concerns.. you have problems sleeping and the antidepressant drugs are making you lethargic and lazy, amotivated.. so, if you have been diagnosed as a case of anxiety disorder or depression, there are antidepressant medications that work as a activating drugs and shud be taken in the morning,,, first of all, if you are facing the side effects with present drugs, and if i am your treating doctor then i will change the drug with activating antidepressant like prozac which can also cause some anxiety symptoms initially.. i would prescribe prozac in the morning with milder anxiolytic benzodiazepine... for sleep, you can ask your psychiatrist to give you hypnotics like, zolpidem, zopiclone etc...if the symptoms were of anxiety mostly then benzos as a hypnotic work best... finally change in a antidepressant drug with hypnotic will work best.. i hope this advice will be helpful to you..best luck..
