Loss of energy and stamina are not uncommon and binge eating has been observed amongst serious Gap sufferers. Some seasons press us to limit our exercise schemes and obliging the pressure is natural and good. Summer vacations and winter holidays beg for time off. Be aware and recognize the safe and friendly boundaries of maintenance training and faithfully heed them until the more favorable times when you can 'blast' with hungry might. Failure to do so leads to despicable consequences.
Prevention is easier than the cure.
Alas, the cure demands that you be so sufficiently distressed with yourself that you're willing to start all over again. Admonishments precede the undertaking of the bitter cure and recovery is a lonely path overgrown with thistle and thorn. Should they recur like a broken spoke on a turning wheel, you can expect that the wheel is going nowhere. Fail to fix and one by one the spokes buckle and disengage. Don't get in anybody's way and don't stop.
