Have you seen what civil pilots actually do? I think if you are leaving purely because of the love of flying, you stand a high chance of being dissappointed.
If part of your love of flying (needs to be a big part) is being in the air and seeing the views then you will enjoy it. Military flying in helos is so far removed from the 'system management' type of flying in modern airliners you may not enjoy the new job.
On the plus side, you will get well paid, albeit it can be a pretty poor home life due to rostering.
Good luck with it if you go for it, I hope you will not regret it, though if the prospect of getting hours in in the military is poor, then it may well be worth the risk of potential boredom.
