One side effect of the allergy shots for me is exhaustion and a lack of stamina. It seems to be most acute between 12-36 hours after the shots, but it really varies on my level of activity. This amounts to nearly perpetual exhaustion because by the time I’m no longer affected by the last round of shots, I’m taking another round.
Now this has not really deterred me from keeping up with the shots and seeing through the immunotherapy. It has however put a damper on my ability to push my self in my work and workouts. I do have a tendency to burn the candle at both ends and several parts of the middle, but I really think this particular lethargy comes from the two small doses of allergen every other day.
Right now, I’m trying to push through while making allowances for greater amounts of rest a night and in the mornings. Hopefully, in the next couple of months my body will start making the antibodies required and the exhaustion level will drop. Perhaps, I should consider taking up caffeine again until then.
