Before you go about throwing money at the problem, consider technique... The first rifle I ever shot was my friend's late father's Savage 99C in .308. I hated the recoil at first - I honestly thought it would be a turn off to rifle shooting in general because it was unsettling. Instead of looking for what gadget I could get to fix it, I just revised my technique and it did the trick; before long, I was shooting .303's with metal bullplates and 300 Win. Mag's without issue, and I'm no superman.
All I did was to make sure that the butt was very snug against the shoulder, kind of like a cheek weld, and that my shoulder was very relaxed and would absorb some of the recoil. That's all there is to it.
Give it a shot, then try the "accessories".
1. Make sure the rifle is pulled snuggly on your shoulder and not free recoiling a bit before bearing on your shoulder. (Yes, I know, the bench rest guys will disagree, but they shoot mouse guns.)
2. Try a Decelerator or Limbsaver recoil pad.
3. Shoot wearing a shooting jacket with a padded shoulder or wear a Past field strap on shoulder pad.
You are going to want to keep using 168 gr bullets with a normal powder charge.

Sounds like you are not holding he rifle properly? A 308 shouldn't beat you up. Make sure the stock and scope are set up to fit you properly, this will help you hold it correctly.

You could always get a shooting jacket...
