Help with heartburn !!!!! and gallbladder removal?

i had my gallbladder removed a year and a half ago now im having heartburn, sweating after i eat, at night i feel like something is coming up my throat and it wakes me up, some heart palpatations. it doesn't happen all the time. Iheard this is common after gallbladder surgery. Also i take birth control pills which may contribute to it, i also take thyroid meds and a diuretic and occasionally doxcycyline for acne which i was told can also cuse stomach issues. so my question is what can i do or take to help or would stopping the birth control pill or antibiotics help? I have had my heart checked and they tell me it is fine and they say it is anxiety, which i know it is not my daughter has that and i am not even close to her symptoms. thanks for any help and tips it is greatly appreciated !!!! btw i am 33 years old
