Sorry to hear about your results. When BOTOX Cosmetic is administered correctly by a trained and experienced injector, there should be a very low chance of adverse results. From what it sounds like, I would check the credentials of this new injector and see what type of experience they actually have with the use of BOTOX.
Because BOTOX affects motor nerves, it is rare to have numbness following treatment. The droopy eyelid might be able to be treated depending on whether it is a drooping eyelid or a drooping brow. You should see the treating physician and have he/she address this. If they are not comfortable treating this adverse outcome, ask them to recommend someone who is. As for the drooling, treatment around the mouth can be tricky and overtreatment can lead to inability to form a tight seal of the lips and, ultimately, drooling. This will fortunately wear off but it may take several weeks to a few months to see a difference. One thing that can be useful is to have a small amount of Juvederm or Restylane injected around the borders of your mouth to effectively stiffen the lip somewhat. This can sometimes help with closure.
