I Have Been Prescribed Cymbolta For Depression. I Have Become

I have been prescribed cymbolta for depression. I have become tired all day and night as well as a bit slow on concentration. I read several forums of other people taking cybolta and also adderal for energy and functionality. I ask my family doctor if I could also try this with the cymbolta. She advised me to take the cymbolta before bed. I generally take it at dinner. I have only been taking it for about 5 days now and all I want to do is sleep. I don't like asking for medications, due to prescription drug abusers. Its hard for us who need these medications, to get them. What can I do? Getting close to losing my job, due to various mistakes. Thank you for your time and advice.
