Aortal Valve Replacement - Day 20

I think i had too much sleep. Head feels a bit heavy and im a little dizzy. Talked with doctor about d fast heartbeat right now. Will have to schedule follow-up consultations initially once a month. He doesn't think it is a permanent condition. Yokatta... (^-^)v Although im still a little worried about it. Warfarin dosage increased again yesterday from 6 to 7 tablets. It worries me that due only to natural variations, my dosage needs to be increased twice in 2 weeks. Especially since blood testing after i'm discharged is only once a month (compared to d current near-daily blood sucking routine). Supposed to have final checkup today but no scheduled examinations yet. Hm.. Could they have forgotten?
