Honestly, I don't know that there is much else you can do to control your bp. I feel your pain... I spent all of my second pregnancy watching my bp very closely to see it go up and develop into PE during and post labour, but I did get my VBAC so I guess it didn't matter so much. I did get concerned about every headache etc for the last 10 weeks. Not much fun.
Stick to the bp meds that you are given, get the acupuncture and try to relax as much as possible. I know avoiding induction would be ideal but at least you know that you got a good outcome last time despite the high bp and induction. Hopefully it will stay just a bit high instead of critically high and you can get to go into labour yourself. My fingers are crossed for you.
