I agree and don't think this is controversial. It is essentially amphetamines. I tried one of these prescribed pills once (only time in my life I have ever taken any kind of drug) and I was awake for 30 hours. It's an extremely powerful stimulant. If taken regularly the body would of course adapt to this.I mean, if you think the medicines are helping you that's fine, i'm just saying from the knowledge and experience i have medicines can't cure you in some true sense, they are just keeping your ADHD on some level adequate for some society, and that's it...
It does not cure, but helps people manage their condition.
Whether or not it gives Biles an advantage it's hard to say, but it could be used for a competitive advantage by someone unethical if used irregularly so that the body does not build up a tolerance. Just take the pills before competition. I've never had that feeling of being alert and unaffected by no sleep before or since. In some countries they hand them out quite easily to people who have had a diagnosis since childhood. Of course, there is no reason to suspect that Biles isn't genuine I am just theorising how drugs could be misused.
Edit- I remember now, i commented list of (not banned) medicine Kamila was using, trying to say there is nothing strange with that, especially knowing it was taken during the corona outbreak. So the choice was to take those medicines, or to stop to compete until her health is better.
