As per my last suggestion, I believe that Roasted Lambs/Red Bulls should not be counted by the hour, but hourly at what time you use them.

How Roasted Lambs/Red Bulls work presently:
-If used before the hour, you lose out on an hour of energy.
For example, if you use at 7:59AM (like I did), that immediately drops to 7 hours of use as soon as 8AM hits.
You must use after the hour (i.e. between 8AM and 8:05AM-ish) to get a full 8 hours.

How Roasted Lambs/Red Bulls SHOULD work:
-As soon as you use them, the 8 hour clock counts. For example, if you use at 7:59. Each X:59, the hour ticks down one and you /always/ get a full 8 hours with it no matter when you consume it.
