I apologize if this is something you have already taken into account, but are you sure the increased battery drain isn't just because you're messing around with it more? When I'm fooling around with JB stuff, uploading themes, trying out new features, etc., my battery life plummets. But when I'm just using it like normal its not so bad.
I have a bunch of JB mods running and do have reduced battery life, but since I find the JB features too useful to give up I just bought a Mophie Juice Pack Air. Now I never have to worry and I can surf and use the phone to my heart's content.
My recommendation is to settle back into your regular usage patterns before deciding the battery drain is too great.
PS. If you want the best of both worlds, there are a few things you can do. Turn of all the MobileSubstrate extensions with SBSettings > More > MobileSubstrate Add Ons; boot into Safe Mode which disables all MS extensions and should leave you with a stock phone; if you are on a 2G/3G and have used SBSetting to turn on the battery % meter, turn that off. Mobile Substrate is the environment that lets you modify the system, WinterBoard and SBSettings are two examples of MS extensions.
