supplementing with formula

i’m 6 months into my ep journey and i’m honestly over it. i’m back to work full time and with the constant clogged ducts from never having the time to pump, and 100 million other reasons, i just want to stop now. i just mentally cannot take it anymore. i have a decent freezer stash but that obviously won’t last forever. can anyone give me any tips/pointers to start supplementing with formula ?
