Now if the potato chip sentence is written in the past we would write: I had had too many potato chips yesterday so I felt sick. Notice the use of had + the past participle? So in the sentence 'I had had too many potato chips so I felt sick' two things happened in the past. First was eating potato chips; second was feeling sick. When you have two past-tense occurrences, you use past perfect to express the action that came first. If you are using the verb 'to have' in past perfect, you need to use two 'had's.
The first example sentence is correct!
