The answer is yes and no.
It really depends on how powerful or low key you want the flavor to be.
Another factor is when would you like to drink it? If you are planning for this Turkey Day or Christmas then I would have to tell you that you are starting too late...others may disagree, but that's my opinion.
Spiced beers require months to mellow out, especially if cinnamon, ginger, or allspice is used.
You could try to "fool" the tongue a bit by using only a quarter of the spices and adding them at the end of the boil if you intend to drink this for this years holidays. The same harshness will be there, just much more subtle.
Plan ahead for next years brews. I always give myself a minimum of 3 months, 6 months would be better.
