Confinement food too heaty?

I’m on my second week of confinement and have been eating all the food nanny cooked. Lots of ginger, sesame oil etc. 3rd day of consecutively drinking red date tea, I felt very dehydrated and started taking water instead. Chugged an entire bottle and that night, somehow my milk supply went up. Now I drink mostly water and some red date/red bean water. However, I’m starting to get ulcers with the food I’m eating and I feel extremely heaty. I don’t usually get ulcers. Worried that I get a fever or fall sick. Also baby looks very flushed and red after drinking my breast milk. Seem to get some push back on removing the ginger in my food from nanny. Managed to convince her to add less. 😢😢😫 Anyone also can’t take too heaty food or struggling to manage that?
