I would of one mad in a matter of days with a diet this strict. BTW, no fruits no greens?

I don't think people can help you on getting you motivated. Why would you be sleepy in the gym alone? I would be gasping for breath already and I felt most alive when I'm in the gym, I'm always sleepy outside.

I work shifts, (morning and night shifts) and I still hit the gym consistently. I've up my frequency recently and I'm hitting the gym around 5-6 days/week. Working on a pull/push/leg program.

I guess the best way to be motivated is to join a gym that is very near and easily accessible. Mine is within walking distance. So you don't wanna join a gym that you have to hassle yourself to reach.

Do tons of reading, lots of the information is available online. Understand how things work and use the mirror as your best motivation.

If I feel tired and not great in general, I won't go around attempting to break personal records. I'll go to the weight that I can do 6-8 reps. I sometime have to skip a day or two for some personal reasons but rarely

It's simple really, my gym is very near as I said and I'm living near my work place as well. I got off work at 5:30pm and I'll be reaching the gym at around 6 or so. By 7pm+, I'll be done already. And I often schedule my gathering or dinner after that which is just nice cause most of my friends got off work after 6 and they need around an hour or so to reach home. For night shifts, I got home early in the morning, sleep and wake up in the evening and hit the gym at around the same time so nothing is really off sync.

I'll take a day or two breaks if I'm going back to my hometown, prolly jog a bit or basketball. Hitting the gym only need an hour or so of your time.

No problems. Erm, I can't really advice much on any vegetarian diet. But I guess you can find a lot of info on Google. Here
