Bisco – I’m not sure, but it looks like your reaction to the Ativan is worse at the dosing times that are close together? What about taking your 4 doses 6 hours apart? I take some pills in the middle of the night.
Alternately, maybe it has to do with your daily biorhythm of cortisol or something. Maybe your body doesn’t need the Ativan at 10:30 and 2:30. Again, maybe moving the doses might help.
Do brainstorm the way Parox suggested.
