You might go up for a few days and then drop back to 5mg. You can play with a little back and forth during the first week. The fact you cant restart does not make you weak. Your body has to have cortisol. Go back up a few days and try to get back to 5mg . Then very slowly taper. Try a 5-4-5-4 for a few weeks. Or maybe a 5-4-5-5-4 .
