Agree with bribo, it really should be time to step back and evaluate your goals. Discus are hyper-sensitive, if your schedule limits you that much then perhaps your energy would be better devoted elsewhere.
Trust me, I'm an experienced keeper and would love to keep discus but my 11 hour work days limit my feeding and water change availability, hence why I do not own them. I'm not suggesting you give up with them, but really assess if it's feasible for you to maintain them. Best wishes finn.
