這個 app 是我自己做給自己用的。 胃在恢復的時候,每天都在猜:剛剛那餐是不是吃了什麼不該吃的?為什麼又胃痛、逆流了?到底有沒有比上禮拜好一點? 腦子記不住這些,紙筆又很難回頭整理。所以我做了 Melly,把每天的飲食、症狀、用藥、睡眠記下來,做兩件事: 一、找出是哪個東西讓我不舒服。 吃了什麼、吃多飽,配上當天的症狀,慢慢就看得出自己的地雷。 二、看自己有沒有在變好。 把每天串成時間軸和趨勢,身體的起伏不再只是感覺,而是看得到的變化。 順便也記錄:今天是療程第幾天、營養品吃了什麼、醫生上次交代了什麼。 如果你也在胃炎、除菌療程或胃食道逆流的恢復期,每天為這些事煩惱,希望 Melly 也能幫上你。 紀錄都只放在你自己的手機裡。
