Stuffy Nose Sore Throat

I am not feeling well since Thursday night.  Could hardly sleep at night as I have to keep waking up to clear my throat and bladder.  I think I am infected by B1 on Wednesday when he offered his drink.  I should not have drank it.  This is the 2nd time I fall sick after sharing drink with him.  I should not have broken the rule.  He is young and fit and even though he is very sick, he does not show as much.  Whereas for me, I feel lethagic and weak.  I need more vitamins to fight my infections.  Worse, I have to get up early tomorrow to go Korea.  It will be a serious week of travelling from point to point and very busy with short sleep cycle.  I will need more rest when I returned home end of next week.
