For you I'd suggest getting up at a consistent time and do the typical prework stuff and get fed, cleaned up and dressed for your day. Also you should initiate a fitness program, nothing crazy but either start with stretching or if already active do home based excersizes. It is very important to be able to stay in shape without having to go anywhere that way you can just keep up with it with nothing getting in the way. Split up and do one set mon, wed, fri, do other in between. It's ok to have a full day off, and don't forget 2 or 3 days with something that gets your heart and lungs working. Good luck, the key to handling this is structure, but also keep mental health and don't make it a grind unless you're desperate. Use some of the time to do fun stuff, socialize (do not drink!!) and explore opportunities and interests. '
