Day 20 is over. This terrible metal taste in my mouth has made drinking water an ordeal to me. Every time I take a sip of water the aftertaste makes me wanna puke. I brush my teeth like 6 times a day but it only helps temporarily. Anyways, fatigue is really settling in. A 1km walk is enough to leave me breathless. Well, the battle goes on and ill check in again on day 25.
