Long text incoming: I've never used medication cause I refused to take any of them, so I'm not familiar with them and their effects. A quick search on google says that it's used to treat depression, OCD, PTSD, Social Anxiety Disorder and Panic Attacks, so Ocean wasn't that far off.
However, it says that the tablet is usually taken daily, but it also comes as a liquid and concentrate, this last one has to be diluted (you can use different drinks besides water for this). It also says that it might take weeks or even longer to give you full benefit, that you should always take it even if you feel good, and if you stop taking it you will experience nausea, sweating, depression, mood changes, irritability, anxiety, tiredness, sleeping issues, etc.
So after this, I came to some conclusions that might explain what happened here:
- Ocean simply didn't know that it's not supposed to take effect that fast, and it could be solved by looking for a different medication OR create their own, tailoring specially to what Nika and Sasha need.
- Ocean does know exactly how Sertraline works, and Nika was just experimenting withdrawal symptoms. How? I dunno, don't have a theory for that one.
