Plagiarism, In text citations

Week 4 has been very challenging for me as a person and a student. As we go further on through each week I find that the assignment seem to get more and more difficult for me. I know that plagiarism is wrong and I try not to use someone else work without citing where I got it from but after going through and trying so hard to get the job done I sometimes find myself forgetting to cite all of my work and giving credit where credit is due. I want to do the best job that I can on this final project but again I find myself struggling to get it done the correct way. If anyone has any suggestions that they care to share please feel free. I would love to hear some input on the topic of caffeine and how it effects the body.
