couldn't sleep

I couldn't sleep last night. Was up every 15 mins it seems. Coughing, or just laying in bed tossing and turning. I'm hoping to get some sleep tonight. I feel so exhausted when I don't get any and I have a sore throat. Just hope I'm not coming down with anything. Work has been stressful the past two days, plus need to catch up on cleaning house. Been avoiding doing that. Just don't have the energy.
Anyone got any good remedies for insomnia?

Hope everyone's day went well?
