Have issues with my BP too. It will likely get better after the surgery. I am almost 3 months post surgery. I feel amazing. Currently 104kg from 126kg pre surgery.
It is the best decision I ever made. For my health, family and may be vanity.
I played football with my 4yo he had to tell me "mum it's okay - lets go in"! I wouldn't even dare before then.
I feel like I can conquer the world. Don't find exercising as exerting as before and hoping to get better.
Let me raise a glass and toast to a new you. Cus that's what the surgery will do! I guess the only downside for me is I can't drink as much alcohol. I feel tipsy really fast. So..... But that too is a small price to pay.
Good luck.
