Plenty of time to sleep but simply cant?

So lately ive been unemployed and able to sleep till i wanna wake up. Problem is i still cant get enough sleep. on average id say ive been getting about 4-5 hours of solid sleep and another hour or two of sleep seperated by tossing and turning. About a week ago i started having sex before sleep and it worked fine i mean cant go wrong. But now even that has not helped my sleep, i just end up horny and tired. I know its not my bed cause ive had it for 2 years and never had any troubles. Other than night-quil and a glass of Jose Quervo Black im outa ideas. And i found jose night quil not very fun, almost scary cause i didnt remember going to bed at all. Thankfully i woke up my fiance. Also tried hot milk. Tastes like melted butter. Any better ideas?
