I took an accidental overdose of my domperidone this morning. I measure out my 160 mg for the day and put it in a medicine box. This keeps me knowing if I've taken my doses or not. Well, I had it all measured out and instead of putting it in the box, I put it in my mouth and drank a glass of water. I realized immediately what I had done. I called poison control. The main concern is if I start twitching. They said the medicine's effects peak at about an hour--which is now. I'm guessing I'm not going to have any problems. I am curious if this will make a difference in my milk supply.
