Narrative:

The aircraft had pack 2 meled. After takeoff and climb to our cruise altitude; the flight was going normal until we got to the area along our route. The captain and I noticed a strong smell of smoke immediately followed by a different strong odor that was more acrid. After smelling the odors; we both put on the O2 mask and advised ATC. We initially thought about turning back; but decided it was better to just continue to ZZZ because of our location. ATC cleared us direct to ZZZ and the captain and I ran the cabin smoke QRH procedures. We were then cleared direct for the ILS X and landed without further incident. Fire/rescue followed us to the gate and we did get checked out by EMS. It was hard to communicate between the captain and I with the O2 mask on. Just simply hard to understand each other. The fumes themselves were the only other threat impacting the remainder of the flight. The best thing I now know is the level of difficulty there is when communicating with the O2 mask on with both ATC and the rest of the crew. As there was a malfunction; I don't believe there is much else that anyone could've done. After initially smelling the fumes; I felt dizzy and light-headed and that slowly went away as time went on. Weakness/fatigue [was] also felt until O2 mask was donned.
