Taking antibiotics is dangerous. It kills the good bacteria, too. When you don't have good bacteria, the bad ones might become more powerful. Then it comes harder to get better if you get sick.
IMHO most people don't know pretty much anything about health issues, including doctors and other professionals. That's why the best way is to choose biohacking and try for yourself to find out what actually works.
I understand it kills the good and the bad, but we also eat a lot of probiotics around here including home-made pickles and water kefir. @corinnestokes keeps me fed with a lot of healthy real food. I also recognize there's a difference between getting bronchitis/pneumonia and not getting it, so sometimes the risk is worth it. I'm going on vacation in a week or so and really don't want to be sick for that, so I figured I'd take the risk in this case in hopes of wiping it out before it got worse.
I have some friends who are doctors and though I agree the amount we know is probably much less than the amount we don't know, but I wouldn't go so far as to say they don't know anything or that all of what they know is wrong. It's a complicated field with a lot of history. It's easy for those who know the least about a topic to think they know more than they do (I'm raising my hand as I say this, since I think we all do this).
What do you normally do when you get sick?
Good to hear that you are using probiotics! It's probably very important, especially after antibiotics.
I'm a biohacker, I don't get sick. :P
Not very often, at least. If I have a cold or fever, just resting for a couple of days is enough. Maybe a little bit extra vitamin D3 and zinc.
