Hi Nonie,

I've only just got my second tri energy and I'm 22 weeks, I can tell you that it's doesn't last all day though, I cleaned the whole house this morning (first time in months), then I was a bit tired, then by 1pm I had a 2 hour sleep So I guess I don't have an unending energy reserve
I guess tirednedd comes with pregnancy and the only cure is rest and sleep, take care....
