Hey - Thanks for all your advice.
I have thought about raising it with HR/Line Manager but I am worried it will hurt my growth if I am seen complaining about the travel - After all (and to be fair to them), thats the first question Consultancies ask you in their interviews - "Are you ok with the travel" , which we all say yes to.
I also gave it a thought last night - And have come to the conclusion that its not the travelling, per se, but this particular project which is quite stressful (No Programme Office, No Risk Management, Blame the Consultant philospohy). The travelling and lack of Support (from the "Mothership", or friends and family), just adds to it.
I think I will stick around till I can take it - If it starts to get too much, I will consider leaving to the Industry - Though all my last 8 years, I have always been in Consulting, so will be interesting to see how it goes.
