Medical waiver (mental) question

[Zehuti]

Quiet Professionals,

As much as I would have liked to find the answer to this question on my own, it seems I am unable to do so. The recruiters in my area are fairly clueless when it comes to SF, and the documentation online for SF and medical waivers seems to either be out-dated or non-existent. I am hoping you guys will have more insight into this. I tried searching the forum for more info, but was unsuccessful.

Put shortly, my friend and I are planning to sign an 18x contract within the next 3 weeks (before our ASVAB scores expire). He went to MEPS yesterday for his physical, and they claim that he needs a waiver for a diagnosis of tourettes when he was young. I heard that certain waiver codes will DQ you from SF, period. Is this true? And if so, is there a resource that lists those? I assume it changes often, but any information is better than none. I don't have his waiver code, but would any of you happen to know if such a situation is a dis-qualifier for an 18x contract?

Additional notes;
1) He has been off medication for over 5 years, and has been cleared by his personal doctor.
2) The paperwork has been submitted for a waiver, but it isn't 100% that he will actually need the waiver, I read that each waiver is on an individual basis; his ASVAB score is 92 and has a 3.9GPA. Do any of you think he has much hope either not needing a waiver, or still being able to sign an 18x contract?

I also read that airborne is VERY strict regarding medical waivers. I couldn't imagine a mental condition that doesn't present an issue anymore mattering, but I would like to get all of the information that I can.

Thank you in advance for any information, and thank you for the tremendous amount of effort and information put into this site.
