Lozz,
Welcome to the OCF.
I'm one of those statistical, almost old man (60), who at age 59, non-smoker and very minimal drinker, developed scc of the lateral border of the tongue. Unlike you, my lymph nodes were clear. No reconstruction of my tongue was needed.
I agree with Mark about a second opinion about additional treatment. The reason I only had surgery was the fact that my nodes were not cancerous. Both the surgeon and radiation oncologist felt that radiation and/or chemo were not indicated in my case. I'm sure that if the nodes were not clear, I would have had additional treatment.
Good luck and please let us know how you are doing.
Jerry
