I Want to Join the Military

I'm trying to join the navy...might need a waiver because i had to go to the doctor and get tested for asthma and they gave me an inhaler during the test. Theyre starting to worry me a little bit because they keep saying they dont know if i'll get through meps with exercise induced asthma on my record. I have a cousin in the navy whos told me that they let people with sickle cell get through meps. I take my asvab next Thursday June 9th and im a little nervous. I guess i'll see where it goes from there.
