Yesterday, I slept rather late before going to work, since I worked rather late the night before. Around 1:00 in the afternoon, while stocking some "paper goods", I started feeling shaky, and my vision kept blurring. Then, the reason why, hit me... I forgot to take my daily dose of blood pressure meds before leaving yesterday morning! Got the same feeling the last time I forgot, but luckily I was home that day. My mom and Andrew came to Wal-Mart about half an hour after I started feeling miserable, so I had mom go to the house and bring my meds back. Took them, and was feeling fine again within an hour, without missing any work.
Just to be on the safe side, in case I forget to take them again before leaving for work, I'm bringing a spare dose and storing it in my locker!
