Hi Sugahorse! I have had multiple sleep troubles-sometimes sleeping way too little, sometimes way too much. I also often have vivid and violent dreams which I feel leave me exhausted.
It doesn't look to me that you sleep waaay more than necessary, most adults need about 7 to 9 hours to feel rested. However, if you are sleeping that long and still feeling tired, then it is possible you are not getting restful sleep. On weekends, if sleeping that long is bothering you or interfering with your activities, then of course you are right to address it!
I am not familiar with that particular medication, but if you feel it has become addictive, it may be producing other side effects as well, which could be affecting your sleep cycles. Would it be possible to talk to your doc about weaning yourself off it? Or, if you need meds to sleep, transitioning you to a different medication?
Sometimes I find it helps to motivate myself to get up when I should if I can do something nice as soon as I wake. Like play ball with my dogs, or have something really good for breakfast, just some little thing that helps make getting out of bed more pleasant.
Thank you for sharing this!
