Although betwattled sounds rude, it's not. It meant confused, distressed, bewildered, stupid. The rather genteel version in Cumbria was betrattlt. This was recorded in Yorkshire in the 19th century:

"Ah's fairly betwattled and baffounded."

From Cumbria, there was this in a verse about a character called Gilpin (1866)

"An' lasses whillyliltit out as they hed been betrattl't."

I can find no definition for the fabulous word whillyliltit. Anybody knows what it means, drop me a line.
