Yeah, I heard that too. That after a certain amt of Benadryl it has the reverse effect and wakes you up.

Only way I can fall asleep these past 3 weeks is taking 2 temazepam, but then I need 1 lorazepam to keep me asleep. Didn't take the latter and I woke up at 3:30 this morning. But, I'm not sure if you're allowed to take benzos when pregnant. Probably not or they would have prescribed them. So sorry you can't sleep. What about triptophan. Maybe you already tried that, but it's the stuff in bananas and turkey and there are supplements for it that concentrate it. Also melatonin. To be honest, those have never worked for me, or eating carbs either. But maybe the combo of all that and the relaxation stuff would help.

Wish I knew more. Take care.
