I have been on dostinex after having found to have tumor bout one and a half years age. My prolactin level which was quite high remains still the same. I have no periods what-so-ever. Symptoms like fatigue, dizziness, stomach upsets, frequent bad headaches, lack of concentration are all bothering me a lot. Though I was scheduled for surgery it dint happen since the dose of dostinex they gave me showed a positive effect. But since then all the side effects originated and they show no sings of subsiding. I have developed certain characters which makes me feel that I am a changed person now. The only problem is that the changes are not good.
