DS's allergist recommended twice daily doses of benadryl to get his eczema to calm down, while we were waiting for all the allergic proteins to leave his system. Last night was the first night in several weeks he didn't get any benadryl. He woke at 4:30 and wouldn't go back to sleep until 6:30 and was majorly cranky today. He cried a ton today took two naps as opposed to his usual one. Threw a fit if I set him down. He doesn't seem to be teething, so my next thought was that the benadryl was leaving his system and that he was withdrawing so to speak. Is it possible?
