I'm going to say that I'm going after you bigger guys here. As I read threw many posts I see a alarming rate of occurrence of people claiming they are tired, lethargic, and just not sleeping very well or at all. I'm also aware that certain compounds and peptides we use inhibit or disrupt our sleep cycles. If any of you have been feeling like your never rested, always tired, and wake each morning in a zombie like state, I would like you too consider sleep apnea. when the throat muscles relax, the soft palate becomes relaxed as well and sags at the base if the tongue the airway becomes blocked, causing limited or possibly stopped breathing altogether. this is common in obese and heavily muscled people. Obstructive sleep apnea has been linked to type 2 diabetes, depression, heart failure, high blood pressure and stroke, very serious stuff guys. I was diagnosed with such a few years back thru a sleep study set up by my doctor. The most common and effective treatment for this is c-pap " continuous positive airway pressure". Since I started therapy some of the many benefits I've had are decrease in blood pressure, decrease in daytime sleepiness, improved concentration, improved libido with more frequent and harder erections, overall better general sense of well being and let's not mention better recovery and gains. for those who have a bed partner it will be easier to determine this by asking how bad do you snore, do I quit breathing and gasp for air? If this post resonates and helps one person I would consider this a success. wishing all my brothers and sisters in iron a healthy and productive new year..
