fratello,
Have you changed anything?
I see you put the WDT back to OFF ... good.
Here's a picture of my breadoard of your circuit, in case you see something different.
Obviously, I'm using LED's instead of relays, but the rest should be the same.
When in SLEEP mode, I measure about 8 µA on my cheap DVM.
The only time it's not in sleep mode, an LED(relay) is ON, so that current is about 7 mA.
Here's the program I'm currently using.
