Sure. I wouldn't know what to do for myself except to think back on what happened about the time the energy collapse started -- started skipping breakfast, not enough sleep, erratic pattern of eating, a switch of something that seemed innocent at the time. Sometimes for me it'll be something that's been working for a long time, and just stops working. Generally then I'll realize I'd been getting little messages of something going wrong for a long time, but I either ignored them or didn't understand their importance. It's like being involved in an neverending detective novel.
