Tell me about it! I've been having trouble syncing for nearly 3 weeks now! I originally used Geth before the attacks started, and after some research I started using Parity and had some success. Since then I have also been trying to sync Geth, and today I was able to do that with the above instructions. There is still another hard fork coming that will get rid of a lot of bloat from the chain, so once that happens then the above instructions should help you out also. Good luck.
