Generally it is not given for sleep as this is primary not for sleep problems.
What sexual side effects you are facing, you have not mentioned.
With antipsychotic medications, decreased libido,ejaculation problems or problems with the erection can come . Generally not seen with low dose bit duration of use may cause problems.
There is need to get
