Side effects - is swim having withdrawal symptoms?

[returntozero]

my friend swim drank a little poppy tea yesterday afternoon. mild experience, dosed at aroun 5p.m. and went to sleep at around midnite

he woke up at around 8 a.m. feeling OK but fell back asleep until like noon and didnt feel too great. he first noticed it when he went to the bathroom and felt like he shouldnt be standing, and needed to go to the couch and relax. swim has been feeling really horrible all day with flu-like symptoms but no fever. aches and pains, lack of apetite, hightened anxiety, and feeling of extreme fatigue.

swim is wondering if he caught a flu bug and this is just a coincidence but i dont know. swim is not physically dependent on opiods. he has tried tea 3 times in the past month or so and has taken some norcos around twice a week during this time span

any help you can give is appreciated because swim has important stuff to do tomorrow and no way he can do anytying feeling like this

thanks
