Hey wildman, I wouldn't be too concerned. There's a million different pathways in the human body, and the hormones could be interacting in an unsuspected way.
Maybe my t-3 levels are raised, causing my heart to beat faster and me to sweat more. Which would be a good thing for me since I am cutting ... I still don't know about the shortness of breath.
Let me put it this way, none of the sides are anywhere near intolerable, they are just starting to show up. Very mild infact, but more than noticeable. This doesn't mean they won't go beyond the mild stage eventually.
Positives: Muscle groups that were soar yesterday, are now about 50% less soar overnight. Felt full in the morning, which is awkward since I am cutting and you are typically glycogen/water depleted upon awakening. For me, *sweating+increased heart rate+increased body temp is a good thing, because I am cutting.
Negatives: Shortness of breath, *sweating+increased heart rate+increased body temp may be a bad thing if you are bulking.
*could be positive or negative
This is just by MID-DAY 3 that I've noticed these things. Also, I have to push my Mid-day workout to evening (damnit) because I gotta head out for a few hours. There's no way in hell I am missing my workout today though, I workout EOD no matter what! hehe, so expect another update.
