If you're withdrawing from opiates for example, your best (legal) bet is to buy some Kratom online, or pick up Immodium from your local drugstore. Immodium is a weak opiate that doesn't cross the blood-brain barrier -- so it'll alleviate withdrawal symptoms, but doesn't have psychoactive effects.
If you're withdrawing from stimulants, the best thing you could get is probably Clonidine or Gabapentin, but neither of those are OTC unfortunately.
It certainly won't hurt to take DXM if you're having WD/s, regardless of the substance though.
