you better ask the doc
id say that maybe you dont need the sleep meds as much as u think.are u taking them coz u never sleep properley?if so it might just be stress
so you are lethargic stressed and on drousy sleeping meds no wonder u are tired
so then u take some ephadrine early in the day u have a long hard day and are very actively stimulated and energetic from the ephadrine,so u get home and when the ephadrine wears off your body is naturally very tired so u sleep like a baby with no sleeping meds needed.so maybe u could give up the sleep meds and exercise intensly so u are nackered and drop off to sleep very easy,exercise releaves stress and u will lokk better which means moves woman,oh yes
i might of read your post wrong i dont know but thats what i seems like to me
