I agree with the b complex and would also suggest lemon juice in water with honey to taste... For Mom I use one tablespoon lemon juice to 8 oz of water...

I am currently on a very very low dose of Lyrica cousin Neurontin( 100mg) and I have been doing the lemon juice..

as for liver enzymes raising doesnt surprise me but I would think the kidneys would be the strain if 90% is urinated out... the 10 might not metabolize right in the liver causeing the upped enzymes... no fun I have to deal with Liver issues with my dog
