My hypos are weird. My mental energy is at an epic high (with very little sleep in between) but my physical energy usually hovers rather low (not as low as depression though) . I attribute this to how long my lows are (months at a time) , and how badly they keep me drained. My longest hypo was a week or so (that was the last one at least, and still unsure if it was part of a cocktail change) , when my depression is usually my "go to" state.

Never increased sleep with my hypos though, just everything that comes with hypo and being tired.
