after surgery I was still on my diaretics for BP, also lasex, which DR did tell me not to continue taking, however my daughter had a miscarriage the day before the surgery, and I totally forgot what he told me. My daughter, a nurse, was supposed to be with me in the hospital to have another presence to listen to instructions, but she was having a dnc, while I was in surgery, and I was thinking more of her than me. ended up in hospital, peeing out more than taking in, with keytones at 2.1, stayed overnight. they took me off all bp meds then my bp started rocketing, and legs swelled up, so it put me a few weeks behind till it all got straightened out. All good now, losing weight consistently. Lesson learned about going to dr, should not have piddled around for so long.
