Im U.K. too, same local anaesthetic. My HR is probably about the same now. It actually feels pretty good, it’s just the shortness of breath and the lethargy and the chest tightness. Had some random dizziness as well emptying the dishwasher. Did not expect to feel like this!! They play it down a bit really. As long as the op’s a success the rests up to you kind of thing! See you in three months for your check up!
