Feeling sick w/a baby sucks 🙁

I'm 9 months postpartum and ran out of my vitamins a couple days ago and whenever I don't take them, I feel faint, cold sweat and nauseous which happened this morning. I ate some bad chicken too last night and have been feeling sick since. I can't get anything down today. Anyone else still taking their vitamins this long after having your baby? Can't get more till my husband gets paid next month either 🙁 It's been really hard keeping up with my son today ugh I wanna feel better!!
