But I only do it 2 - 3 times a month, not 18 times a month
2-3 times a month at what 4 or 5 days a shot?
As for 18 times a month I just did 11 days in a month, 20 days off, for maximum hours and 3 nights away from home, and I have done the longhaul stuff and I say no thanks!
All for their own when they are new! ^^
