Hi T.G. and welcome to the A/P.
If you find your Rx too activating when taken at night...then yes, switching your dosage time to the a.m. is a good (and common) change to make.
Please also see our Resources at the top of the main forum page here for great self help material to help reduce stress and induce relaxation.
I hope you find these steps helpful and get the rest you need.
