Adderall XR and panic attack

I have had really bad anxiety and panic disorder for a year now from being a former pot smoker. My doctor prescribed me adderall xr 20mg after I asked her to. I'm in college and I have a friend I go to school with who takes it. I found out about it from her and she gave me a few. When I took it I was fine. Even the come down wasn't as bad as what I am experiencing now. I took the first pill out of the bottle yesterday. The first 5 hours were great. I was focus on what I was doing and I had no anxiety or weird side affects what so ever. Around 2am I started feeling dizzy, fatigue, parts of my body was going numb, my limbs were getting weak and they hurt, i got massive migraines, chest pains, weird shots of pain that felt like lightning going up my spine to my neck, blurred vision, and my speech was slurred. I did not want to wake my parents up because I thought maybe i was just having a panic attack. My doctor put me on metadate prior to adderall and I had some panic disorders with it, but this was far worse. Then I realized that all of these horrible feelings couldn't be from anxiety. I usually just get the rapid heart beat, short breath, numbness due to hypertension, and chest pains. This was far worse! I felt like a thousand needles were poking into my chest, at time I felt so weak I thought I was going to faint, if I got up too fast I got dizzy spells and everything became a blur to me. I was so scared that I felt like I was going to die. I had read the papers given with the drug and it said to seek medical attention immediately with the symptoms that I had. I didn't want to do anything drastic like call 911, because thats what I did with the metadate and over time i felt fine, so instead I called the poison control hotline on the pamphlet. The woman over the phone said that what I was experiencing was normal and that everything only seems more intense because its late and i'm tired but I can't get any sleep. Her voice and assurance made me feel slightly better, but afterwards things just got worse. I don't understand why this drug had these effects on me when I took the same thing before with no problem! During that time I had anxiety as well, and I still did not have any issues. I love the fact that this drug helps me to remain focus, but the after affects are so horrible. Does anyone know if I can just sprinkle half of the pill in some food or something and I won't have these problems, or if there is something equivalent to adderall without those horrid side effect?

I was finally diagnosed with add last November. The doctor tried me on Straterra. It made me tired all the time and emotional. Next we tried Concerta. That made me agitated and irritable, So then we finally got around to adderall. It worked, yay! 10mg 3xday did nothing for me, so the next time I went to my pdoc I told her. So she upped my dosage to 20mg in the am, 10mg at noon, and 10mg in the pm. I did not understand this. I tried this for a few days and guess what? I did okay in the am, but the noon and pm dose were useless. So I took it upon myself to just go ahead and take 20mg 3xday. Only side effects were dry mouth and appetite reduction. I ran out a week early, but no biggie, I was prepared for the consequences,
So the next time, I see my pdoc (new one this time), I tell her what I'd done and I felt that 20mg 3xday was right for me. She recommended adderall xr30mg in the am and 20 regular adderall in the pm. I decided to go ahead and try it, figuring xr is the same stuff in a time released form.
Oh how wrong was I! Side effects started with headache, then drowsiness to the point I had to take a nap. I've been becoming more and more emotional and irritable since I've been taking it (2 weeks now).
Earlier tonight I had an episode that could have turned into a bad panic attack. Luckily, though, I got to my clonezapam before I got too far out of control.
I just don't understand how the (supposed) same drug in a different form could have such different side effects. I was going to continue with the xr, hoping the bad side effects would diminish in time, but after tonight, I think I will flush them.
Has anyone else had the same or similar experience?

numbness in hands, sometimes sooo bad it hurts and wakes me up in the middle of the night. Anyone else have this expierence?
