Capecitabine and taste buds

My partner has just finished her first stint of chemo taking Capecitabine, anyone got any insight into how long will it take for her taste buds to return and, as stupid and as trivial this may sound, how long before she may enjoy a cup of tea again. She was a big tea drinker and hasn't enjoyed a cup for most of the duration of the chemo, she's really missing the enjoyment of a lovely cuppa.
