..simply comes off! I'm on holiday right now and submerged in water for a good chunk of the day. My patch peels off - not really surprising. What to do then? Have a few spares with me but not to change daily. Is it better to change as frequent as I can and have days without cover or not bother and stop for two weeks? I can't bear the thought of mood swings coming back, otherwise the aircon will take care of the hot flashes I hope:)
