  Giant eruptions (GE) in Luminous blue variables (LBVs) are years to
decades-long episodes of enhanced mass loss from the outer layers of the star
during which the star undergoes major changes in its physical and observed
properties. We use the \textsc{mesa} stellar evolution code to model the
evolution of a $70~M_{\odot}$ star that undergoes a GE. We let the star evolve
to the termination of the main sequence (MS) and when it reaches $T\simeq
19\,400 $ K we emulate a GE by removing mass from its outer layers, at a rate
of $0.15~ M_{\odot}~\rm yr^{-1}$ for 20 years. As mass is being lost, the star
contracts and releases a substantial amount of gravitational energy. The star
undergoes an initial $\simeq 3$ days of expansion followed by years of
contraction. During that time the star tries to reach an equilibrium state and
as a result of loss in gravitational energy, its luminosity drops about one
order of magnitude. As the GE terminates, we let the star continue to evolve
without any further mass loss and track its recovery as it regains its
equilibrium by adjusting its internal structure. After $\simeq 87$ years it
reaches a state very close to the one where the GE was first initiated. We
suggest that at this point another GE or a cycle of GEs may occur.
