Food to avoid during breastfeeding?

Hi, I am currently on confinement and I would have to eat fish, dishes cooked with some alcohol and drink herbal soup everyday. I have a few concerns of the following: - does the amount of mercury in fish allow me to breastfeed safety? - if the dish is cooked with 1-2 tablespoon of alcohol, how long should I wait before I pump? - does the herbs in the soup affect baby? Thanks
