How to get a soldier in a WTU

 I have a soldier (88M) that has been diagnosed with a heart problem. Soldier was in the process of chapter before the diagnoses for always being late. Now that the soldier has been diagnosed all chapter process has stopped because of pending Med Board (at least 8 more months because of treatment needed). Soldier has a Dead man Profile can’t be outside if temp is below a certain temp or above a certain temp. No lifting, bending, standing, or climbing. No ACH or other gear. Ok now the problem we are having. Soldier has difficulties waking up in the morning he claims it’s because of the heart condition. We call ever morning no response, we send people by is on post house no response. We have counseled this soldier 14 in the last 60 days for FTR. We are being told to just keep counseling him for being late. The soldier is no help to the unit or mission we are already at 50% manning. I have exhausted every idea that we can think of. What myself and the soldier have talked about trying to send him to WTU but according to his case manager she said he does not fit the requirements to go. Can anybody point me in the best direction for this soldier’s best needs?
