My biggest issue is the food issue, and burning through so much while mining and the lack stamina that follows it. In 18, I could pretty much swing the iron pick without draining my staima at similar levels except I hardly ever used sexy Rex, and now I've got two levels and seems to little effect. I've found little food/meat or seeds to grow my own food. So I basically have to give up mining until I find a lot more food or an auger.
