Bread soup symptoms and conditions

I am taking Septra for a sinus infection. I am consistently, ridiculously nauseous all day and all night since within two hours of my very first dose. Taking this medicine with lots of or little bits of food, milk, bread, soup, peppermint tea, ginger, etc. doesn't make a difference.
Food smells make me wretch. I can't even wash the dishes because of the leftovers. Even simple mention of some foods makes me gag.
I also am sick when the road curves too much ahead of me, I see spinning things, and moving my eyes too quickly.
I have never been this nauseous in my life. I find it disturbing.
Vomiting does not relieve the sensations. My vomit tastes very bitter.
I suspect the accompanying headache is from dehydration caused by the low food intake and diarrhea.

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?
