Okay, so the drops do seem to be affecting her blood pressure/energy levels after administration and in the evenings. She becomes disturbingly sleepy and limp with an unsteady gait and it's worsening with each dose. 
   
I've read about the effects in humans, but the only solution is to reduce or discontinue the drops. I'll be discussing how to proceed with my vet, but has anyone else had this issue with their Yorkie and if so how did you resolve it? Thank you.
