Carbs?

Hi!

I have been stuck at the same weight for weeks, and after evaluating what I have been eating I realize I don't really know how many carbs I should be consuming.  I know I am consuming too many but what is the range for someone 9 months out from surgery?  Any suggestions.  I do get 60-70 grams of protein in (I work out 4 x a week) but have no idea what I should keep my carbs at .  Any suggestions, appreciated!  Thanks!
