you sound like my dad used to be before he retired. he ran a whole plant all by himself. on call 24x7x365. and he couldnt even take vacation unless this other guy was free to take his place those days.
i used to feel that way when i was in operations. but since i've been in engineering i dont feel as stressed. i go home and dont really worry about work unless we've been having problems earlier in the day or i know some upgrades are happening that day. and since we have a pretty decent sized group, the workload can be spread between all of us, so it works out pretty well.
so as somebody else stated, i dont think it's an IT problem...you probably just need to find another company to work for...preferably one with a larger IT staff
