Hi Nevvie, yes it’s hard to work full time and study part time! I did that for a few years.
Some colleagues, suppliers and customers I worked with were super supportive when I told them I’m studying part time and we worked out arrangements where I send them some documents in advance and they will help me settle it earlier before my exams or resolve for me so that I can spend less time on it.
I make my own fruit puree energy drinks for brain fog days by boiling blueberries with 10% sugar + some water if needed, store in a glass jar for a few days. I drink a few tablespoons of it with warm water. Or bring a fruit salad to work. It helps me stay alert for a while.
