How not to plan a roster

My last cycle has been:

Day 1 - Leave home 2330, fly 1:30 to Male, fly 1:30 back, get home at 0530 (on day 2).

Day 3 - Leave home at 0550, fly 1:30 to Male, fly 1:30 back, get home 1145.

Day 4 - Leave home at 1120, fly 3:30 to Karachi, fly 3:20 back, get home 2145.

Day 5 - Leave home at 2230, fly 2:20 to Bombay, fly 2:20 back, get home at 0700 (on day 6).

That's about 24h "rest" between duties, which makes resting difficult. Going to work at bed time and adjusting your body clock 12h every day is effectively impossible.
