ADHD medicine

I went to the dr. today to get some medicine for ADHD. I thought it would be a long drawn out process, but the dr. came in and said, "So, do you have ADHD?" I said yes. I told him I've read books about it, and that I was a school counselor so I know about it. I haven't wanted to do medicine until now, because now it's at the point where I can't do 4 kids and homeschool and be the kind of mom and wife I want to be without making some changes. He said, "Do you have a medicine you want to start with?" I said Adderall XR. I said I wanted to start on a low dose. He said he usually starts at 20mg which is about a medium. I said I'll start out at 15mg and come back in a week. He said ok and gave me the prescription. Cool! I went straight to the pharmacy and got the medicine. I took the medicine at 12:22 and it's now 4:24 and I have noticed a huge difference so far. First, my mind doesn't feel like a tornado. I feel calm and focused. Second, I don't feel overwhelmed. I feel calm and feel able to handle things. I am able to concentrate and focus. I was doing something and I got a text from Todd to check my email about something exciting, but I was able to not get distracted and wait until I was done with what I was working on before I checked my email. (More about that email later). I was reading and I was noticing a huge difference in my ability to focus and absorb what I was reading. Before today, I would have to read something over and over again to absorb it. I also feel more patient. I interrupt people because I am too impatient to wait for them to finish what they are saying, but when I was talking on the phone, I felt so much more in control and able to be patient and not interrupt! I feel so much more in control= less impulsive. And this is only a low dose, and the first few hours!! I have been taking medicine for anxiety and depression, which is often a misdiagnosis for ADHD (but can also coexist with ADHD) and after a few hours of taking this medicine, I'm thinking that I don't have anxiety and depression, just ADHD. I thought I'd feel side affects (one good side affect though is appetite suppresion) but I don't feel any. I know this isn't a magic pill that will fix all of my weaknesses, though, but I need this in order to make my efforts successful. Taking medicine, along with exercising and doing the strategies I'm reading about in the ADHD book will hopefully make things a TON better for me and my family. One bad thing about this medicine, though, is that I can't nurse anymore. I do think that the benefits to all of my family is worth it, though. I do feel bad that I can't nurse, I've nursed all of my kids, but at least I could nurse her for her first 7 weeks. I know nursing is important, but only me and my family know our situation and can weigh out the pros and cons. I'm worried about people giving me guilt about not nursing.
I will post about Todd's email later, because I have to do a lot of backed-up cleaning and other things!
