I have been using humalog many years 2 or 3 times a week before workouts. Of course, before 10 iu before workout i have my carb drink and other supplements. I feel insulin does stress out the body to work harder, shuttle in all the nutrients but too much is not good if u have other health issues. Im was finding i was getting smaller . Maybe the insulin was worsening another health condition i was experiencing. I was getting major itchy rashes on my arms and at time other parts of the body.This has been going on and off for 4 to 5 years. I couldnt figure it out . I had other symptoms like fatigue,digestion problems ,pain,insomnia.... After a ton of reading , im thinking i have had candida or leaky gut. candida is when the bad bacteria in the gut overgrows and many sweet carbs with make it worse. Has anyone gone through something like this?
