Yip worry makes it worse, especially if you check the time. I've covered the click so I can't see the time, I have to get up to pee and have a sip of water and sleep again sometimes. Otherwise I used to get up and do all my ironing and baking while my husband snored...
Now I just drift, sometimes going back to sleep but waking late for work! Vicious cycle. Relaxing about it is the only option I can recommend....good luck
