I still practice and compete. I just took gold at NAGA this weekend! I can still make about 5 days a week if I am careful with my time budgeting. I don't spend a lot of time on anything besides studying and BJJ/MMA though i.e. TV, going out on weekends, etc. Second year will be more of a challenge apparently. Some friends of mine in 2nd year said some months they can make 1 day/week, other months aren't as bad. Jiujitsu and medicine both seem to be a marathon not a sprint. As long as you know you're in it for the long haul and always make your return to jiujitsu when you can, I think you'll be good!
