You need to be square with the doctor about EVERYTHING right now, not just the tamer stuff. You cannot afford to go into full-blown destabilized psychosis when you are the sole caretaker for your son. That is your responsibility as his parent. If the doctor doesn't know exactly what is going on with you, he cannot fully assess your condition or make the most accurate adjustments to your meds. You need to do whatever needs to be done for the best outcome, safety, and well-being of your son during this time. If that means IOP, then that is what needs to happen.
