Eastbound star after lower transit

If you shoot an east bound (circumpolar) star some time after its apparent daily lower transit has passed (its coming back up toward the east), the LHA from me is greater than 180 degrees.
Do I run into any funky trouble on the halfsum method or law of cosines method of solving for my longitude, or solving for Hc (St Hilaire), if using that method? OR does the beauty of cyclic trig functions save me the pain?
It would seem my "spherical" triangle is wrapping more than halway around the Globe.
