History: w1d1 completed last week after 3 tries. criteria for completion was simply making it through all 8 jogging intervals without having to stop jogging during the run sections. Today I took at stab at successfully passing w1d2. My criteria for passing this day is that I finish all 8 intervals without feeling dizzy/pukey/jittery. I found last week (and again today) that by interval 7 I start feeling those things. I force myself to run through them, but I know it's not good/normal/healthy to be feeling those things during the cardio. I will keep repeating this day until I pass. I'd like to find out what is causing it- possible culprits include low blood pressure, low blood sugar, lack of oxygen (pushing my heart too hard/going about my max output), or heat exhaustion. It was cooler today- only in the 80s, so I don't think it was heat exhaustion. I'm going to take my pressure and sugar readings before and after my run on thurs to try to shed light on the problem
