Luckily I've a phased return but oh god it was harder than I thought. I managed okay until the last hour and a half then my energy crashed and the body aches and heart palpitations kicked in. I had to go to the doctor after work to pick up paperwork, collapsed on the couch for an hour when I got home until I summoned the energy to wash and eat, and my eyes were itchy/watering like crazy all evening. I woke-up this morning feeling like I have the flu. My throat is so painful but I need to keep reminding myself that it's not an infection.
So glad my next day of work isn't until Tuesday. I'm working three days next week (Tue/Wed/Fri) and have people coming in from another site Tue/Fri to help me out. My boss came to see me for a chat yesterday (he is also the person helping me on Friday) and he said it is good I'm back and we'll just have to be a team while I adjust. I work solo in my role and the requisitions for next week already look intense (and I'm still waiting for half the department to get their sheets in) but I'm glad I've such great support in place.
