Ex post editto....I might give that a go as it is the VA Dr's always try to off label treat me so I have like 5 pounds of medicine to treat my animals with for free. It is almost always the same stuff my DVM prescribes.
Edit- I meant the b-12 might work for me LOL
(Smirks) as for my experience, I "feel" a difference with 2500-10K IU for some days. Our kiddos have a good reaction with 1K-5K IU chew tabs.
