Trelstar Hormone treatment side effects

Finished 7-1/2 weeks of IRMT radiation treatment.
PSA went from 0.4 to below 0.0
Also on 6 months hormone treatment
With the 2nd 3 month shot i have developed a real problem with sleeping.
Either cannot get to sleep or wake up every hour or 2 and cannot go back to sleep.
anyone else had this reaction?
