The only resources I have gotten consistent help from after being at the PEB is wounded warrior, the VA 1000 number, and Jeff at the PEB.
The 1000 number can tell you super helpful info but it is extremely inconsistent. Like I'm talking 10 agents will tell you 10 different pieces of the puzzle, and the 11th agent will know everything and will tell you everything or send you everything.
Wounded warrior gets status updates weekly from a supervisor but it is typically one week behind from the truth.
Jeff can be super helpful, but he will be brief in his update and you won't be afforded time to ask questions most of the time unless they're fast and easy to answer. Be nice to the guy, I wouldn't know what to do if he stopped answering these calls.
You and I went to the PEB stage on the same day. My proposals are with the PEB now and I only know that from harassing the 1000 number enough to get an agent to send my findings and another agent to let me know the PEB was forwarded my findings.
