Respiratory Acidosis

Practice Essentials Respiratory acidosis is an acid-base balance disturbance due to alveolar hypoventilation. Production of carbon dioxide occurs rapidly and failure of ventilation promptly increases the partial pressure of arterial carbon dioxide (PaCO2). [1] The normal reference range for PaCO2 is 35-45 mm Hg. Alveolar hypoventilation leads to an increased PaCO2 (ie, hypercapnia). The increase in PaCO2, in turn, decreases the bicarbonate (HCO3–)/PaCO2 ratio, thereby decreasing the pH. Hypercapnia and respiratory acidosis ensue when impairment in ventilation occurs and the removal of carbon dioxide by the respiratory system is less than the production of carbon dioxide in the tissues. Lung diseases that cause abnormalities in alveolar gas exchange do not typically result in alveolar hypoventilation. Often these diseases stimulate ventilation and hypocapnia due to reflex receptors and hypoxia. Hypercapnia typically occurs late in the disease process with severe pulmonary disease or when respiratory muscles fatigue.

    I'm not going to buy sticks or strips to pee on to tell me if I am in a state of ketosis or if there are ketones in my urine, however, I have a question
    For the first 7-10 days, I could (I believe) taste in my mouth when my body would go into ketosis. It's a fruity, almost metallic, something in between sort of taste.
    Sadly, I have no one I can breath on to sniff and tell me what it smells like to them to know if I managed to make it into ketosis. So my question is, what other means can I know if my body is properly dropping into Ketosis?
    I only ask because ever since my Meatza from 2 nights ago, I havn't tasted that familiar sensation a single time. And that worries me. I love this sort of diet because I get to just scarf down meat and cheese (and bacon!) like it's going out of style. TBH, I'm not even bothering to watch my total caloric intake yet, because I am simply watching my portion sizes and really acting as scared of carbs as I can be, and I'm hoping that takes makes the weight fall off. But I really like that taste in my mouth which I believe to be my body entering and maintaining a state of Ketosis, and am curious for anything else I might be able to tell from.
    Other than that, I am also beginning a fairly aggressive gym routine to coincide with the Keto, it will consists of 3 days of running, and 2-3 days of 'Muscle Failure'. The last time I was on a High Protein Low Carb diet it's what I did, and it worked out great before. It's also really simple to follow, 1 hour of running treadmill (or walking) on Mondays and Fridays, on Wednesday you do a 30 minute session. Then on Tuesday Thursday Saturday, you work the muscles. I started last night with the run (but since it was the first day I did the hour long session) and made it 4.11 miles on a treadmill, with a 1.0 incline to compensate for indoor running on a treadmill. My "goal" is to run 6 miles in an hour @ a 1.0 incline, without having to 'slow down' to a walk like I had to do numerous times yesterday. And then just build from there. As far as the muscle failure goes, I just want some muscle to look good in the mirror, and to look good for the ladies. I'm not going to kid myself, I'm doing this as much for myself as I am to bag a hottie. Plus being in shape and healthy is always a huge plus.
    So
    TL:DR ; besides distinct taste / breath, and peeing on sticks to look for ketones, are there any other solid signs of Ketosis?

    simply consuming 20g or less net carbs a day ensures ketosis. some people can handle more but 20g seems to be the point of assurance.

    That's my problem, I used as 'low carb' of a sauce as I had in my cupboards, so it was this weird off brand I must've bought at some 'cheap grocery store' like a Aldi's or something. It had a lot less sugar than the Hunt's in my cupboards. So for the meatza, I did only eat 1/4th of the entire meatza, but it still ... I don't know, I know nothing else I really eat through the day has any carbs in it. And then I made some Caveman Keto Chili last night, so more tomato sauce (couldn't find my paste) from the same can I had transferred to a fridge safe container, so more 'not a lot of sugar but definitely sugar in it' and that just worries me.
    Like today, I'll eat
    http://cavemanketo.com/chorizo-breakfast-casserole/
    This for both my breakfast and my lunch
    And tonight I'll eat
    http://cavemanketo.com/caveman-chili/
    So I'll hit 27 total carbs today, assuming I followed the recipes appropriately, but I'm not doing any amazing job of keeping the numbers solid. I pretty much use one entire green pepper to prepare these dishes, so for the breakfast dish it's one half of an onion , and one entire green pepper
    The same goes for the dinner dish, I use the OTHER half of the onion that was left over, and one more green pepper.
