Tom, start getting your ducks in a row now, including your wedding....LTR is right, don't do something you will regret.
So, if i were you....agree with the doc, go back to him now and tell him your fine.....this way, your medical records reflect and your diag. with BFS. Then, get you a good disab. policy and life policy, becuase, you will have to "honestly" answer the questions and with a referreal to an ALS clinic, you will get nothing, so make sure you do the right thing first. If it is ALS, then there is really not a whole lot you can do anyway.
Regarding your life cover at work...just about all life policies have a "disability clause" in them which is life threatning, which in a nut shell means that if you have to leave work becuase of a disability, the life insurance automatically stays in place for the rest of your life and the premiums are waived, so you do have life cover, even if you have to leave work from the disabilty, otherwise, life insurance for workers would be a gimic...imagine, you get hurt, stay in teh hospital for a month, then die....."the life cover still applies"....it's the same with any disability. I've done my homework with mine, but it's pretty standard. You should get copies of all your benefit packages.
You may also be able to increase your life cover at work, which would be a real easy option...
IN any event, i wouldn't go back to a dr until i'm approved for everything..
rgds,
