Can I Join the Coast Guard Having Voluntarily Been in Rehab for Alcohol?

Thinking of joining the Coast Guard and need to know if you can join having been in rehab (For alcohol. No Drugs). It was 2 years ago and I no longer drink and I am in good shape. The only thing I can find online is rehab for drugs, and it was for alcohol. The 2 are related, but a little less severe (In my opinion). Thanks for any help on this
