I have a wonderfully supportive wife who puts up w/ smelly workout clothes and disapearing for long runs and rides and weird tri/running friends BUT she's really getting fed up w/ my passing out by 9PM. I also want quiet time w/ her but when 9PM rolls around I start winding down. she wonders about the impact of marathon training and meds (glucophage,amryl, prandin) have on me. any thoughts?

I agree - family comes first. However, we all have things that can temporarily disrupt our schedules... So, if you're training hard but have an end in sight (big race in few weeks), you can reassure your wife that things will get better after the race. If you're just in regular training, though, it might make more sense to back off and find a bit more balance. And I've found that flowers always help, too. Finally - read up on high energy foods. They can definitely help - and a 16 oz. Diet Rock Star can help me be look alive most evenings.
