I am now 15 months post op and have been doing fairly well, back at work part time, eating better and pacing myself. However yesterday afternoon in the supermarket I realised that I was having a partial blackout, felt very dizzy and headed for the exit. The problem was, although I have been going to the same supermarket for 25 years, I didn't know where the checkouts were. I completely lost my orientation. Luckily, a shop assistant saw my distress and found me a chair and fetched me a glass of water. After about 10 minutes I felt better and was able to drive home, had a mug of tea and a short nap and felt fine. I hadn't been doing anything different to my normal routine earlier in the day and had eaten as normal about 2 hours earlier. Has anyone else suffered a similar episode?
