Patient?

Ive never heard of pill hangover, maybe the patient is implying withdrawal symptoms. If it’s something like a narcotic pill, oxycodone and the like, then there are medications to treat the withdrawal.

There are also benzos, antidepressants, and other types of “pills” that produce a kind of withdrawal and all of them would benefit some kind of medical intervention.

Home remedies have their place, but some withdrawal symptoms can be life threatening. Advise this person to go the hospital to be monitored.

What kind of pills?

So many things come in pill form…

Hydration is probably still a good start. Helps your organs (including kidneys) do their jobs.

Hydration, carbs, and anti-inflammatories.

Make sure the hydration includes electrolytes.

Most of the pills that are abused enough to cause a hangover are going to benefit most from the hydration. It’ll flush out any water soluble stuff a teeny bit faster and support the entire system.

Beyond that, it’s time.

Sounds like withdrawal. Quite the pickle, Don Dickle.
