Because I take my entire dose of bipolar meds at night it knocks me out and I don't recall dreams. Sometimes I don't even remember falling asleep... that is when I wake up with the light on and my book in my hand. If it is cooler weather, which is most of our year here, I just enjoy being warm and comfortable. I used to have anxiety about falling asleep but after years of consistently being knocked out I have no more worries. However, if I forget to take my meds I barely sleep, waking up every half hour. I usually wake up more refreshed though after alight like that then a full nights rest on my meds. Funny that. But, I will never stop taking my meds because being in the hospital is far worse than any side effects the meds have on me.
