Can't Taste Food

It has been 10 days plus since my return.  I have only been able to taste tea and fruits since my arrival in SFO so I haven't bothered with cooking and have only been eating instant noodles, no taste, no inspirations , no cooking tonight was the first time I was able to taste other foods like corn and veggie tuna sushi and samosa.  I guess I am exhausted from my trip.
