Aw - I'm sorry to hear that, but your health must always be your priority - and you've been through the mill lately so I'm not surprised you're completely knackered.

Best wishes for recovery (and I can sympathise with the numb mouth thing after having a wisdom tooth out - it took 3 months for one side of my mouth and jaw to get feeling back - but it does come back) and I'm looking forward to next year already!
