"my sleep problem is describe as: ease of falling asleep; extreme-difficulty staying asleep for more than three hours; however, mostly-pleasant dream occurences. i take ambien occasionally in attempt to fully replenish my body&#039;s energy-level. to not become dependent, on occassion i will try rozerem. the problem then becomes, each time i take rozerem, it causes me to sleep very lightly with what some may consider &quot;intense-viagra effect&quot;. it is only after i take some measure to resolve this effect that i then am able to obtain a deep sleep for about five hours; but this deep sleep is always accompanied by what i consider extremely unusual or unpleasant dreams."
