Thanks everyone, for trying to answer my questions, and I'm very sorry to hear of your particular experience MrsDarcy.
After much searching on google, I found this info below, and discovered that reassuringly, Bromocriptine does not hold any adverse effects on the mother AT ALL, it contains dopamine (the thing I'd heard about...) and that boosts seratonin and is usually used in treating parkinsons patients...:
"Drugs that may suppress lactation
Besides medicines that affect the infant, there are also certain medicines that suppress lactation. In some instances, these medicines are used if the mother has decided not to breast-feed. On the other hand, Sisters need to counsel patients that these medicines may affect the quantity of breast milk produced.
There are several types of drugs that may suppress lactation. These include:
Bromocriptine (e.g Parlodel®)
High dose pyridoxine - B6 (e.g.Beesix®, Lactosec®)
High dose oestrogens in oral contraceptives (e.g. Nordette®, Nordiol®, Logynon®, Ovral®)
Diuretics including loop diuretics and thiazide diuretics.
Bromocriptine and high dose pyridoxine are both used to suppress lactation when the mother does not want to breast-feed any longer. Bromocriptine is usually the drug of choice if the mother does not want to start breast-feeding at all and pyridoxine is usually used in mothers who have decided to stop feeding their child at a later stage. It is often not necessary to use medicines to suppress lactation and many women find that the milk supply diminishes as the infant takes less at each feed due to the diet being supplemented by an increasing number of solids.
Bromocriptine acts by suppressing the prolactin secretion from the pituitary gland that occurs after parturition. The usual dose is 1,25mg orally on the day of delivery followed by 2,5mg daily for 14 days."
