Kris - glad the Aldomet is doing the trick. I'm on the same dose... 2 per day. I'm getting better at remembering. I have one after my morning shower and one at dinner time (with my blackmores preggo tablets). Time will tell if it's working but I haven't had a headache since so maybe they are working? I usually get blood-pressure headaches every now and then.
Your own BP machine sounds like a plan. I wonder if you can hire them? They'd be handy toward the end of the pregnancy. Gawd, the amount of times I had my BP taken... and they always had to track down the large cuff. I couldn't believe how the whole ward only had 1 large cuff!
