Every time I try small doses of mast prop my prostate swells and I have trouble urination. I’m extremely sensitive to that drug. But low dosages of Proviron work well for me.You describe typical side effects of cabergoline.
If you had a prolactinoma at one point that required an Endo to prescribe caber then you should know that prolactinomas shrink over time with dopamine agonist treatment and cessation of drug therapy can usually occur in 6-18 months.
Might be time to titrate down to .25mg 1/week and then go off. 250mg l-dopa/day for a few weeks afterwards would be fine.
Other things that can help, 100-150mg b6/ day and 20-30mg mast prop per day.
