Welcome to the site - I'm not sure how losing your license will effect your obtaining a professional license in another field. I do know that most professional licensing includes a background check so if your situation included a misdemeanor or felony conviction you will likely have issues.
Have you had any treatment? Are you currently sober? Are actively working a program of recovery with NA?
If you can answer yes to any or all of the above you need to include that info with your application. Depending on the state you are in reinstating your nursing license will involve a considerable amount of hoop jumping. The best thing if you can is to consult a lawyer with experience in these matters and decide how best to proceed. You may be able to get a probationary license but would likely be required to attend 12-step meetings and submit to random UDS for a period of time. None of this should be a problem if you answered yes to my three questions. If you are in California PM me as I can help you with the requirements of that state. I was in the California Diversion Program for 4 and 1/2 years. I have been sober for 7 years and have a job in Nursing that I love. The past is sort of like a bad dream - but not all bad as that experience saved my life.
