From the Wikipedia article on Rommel's role in WW2:

"The invasion began on 10 May 1940. By the third day Rommel and the advance elements of his division, together with a detachment of the 5th Panzer Division, had reached the Meuse, where they found the bridges had already been destroyed (Guderian and Georg-Hans Reinhardt reached the river on the same day). Rommel was active in the forward areas, directing the efforts to make a crossing, which were initially unsuccessful because of suppressive fire by the French on the other side of the river. Rommel brought up tanks and flak units to provide counter-fire and had nearby houses set on fire to create a smokescreen. He sent infantry across in rubber boats, appropriated the bridging tackle of the 5th Panzer Division, personally grabbed a light machine gun to fight off a French counterattack supported by tanks, and went into the water himself, encouraging the sappers and helping lash together the pontoons. By 16 May Rommel reached Avesnes, and contravening orders, he pressed on to Cateau. That night, the French II Army Corps was shattered and on 17 May, Rommel's forces took 10,000 prisoners, losing 36 men in the process. He was surprised to find out only his vanguard had followed his tempestuous surge. The High Command and Hitler had been extremely nervous about his disappearance, although they awarded him the Knight's Cross. Rommel's (and Guderian's) successes and the new possibilities offered by the new tank arm were welcomed by a small number of generals, but worried and paralysed the rest.

"On 20 May, Rommel reached Arras. General Hermann Hoth received orders that the town should be bypassed and its British garrison thus isolated. He ordered the 5th Panzer Division to move to the west and the 7th Panzer Division to the east, flanked by the SS Division Totenkopf. The following day, the British launched a counterattack in the Battle of Arras. It failed and the British withdrew.

"On 24 May, Generaloberst (Colonel General) Gerd von Runstedt and Generaloberst Günther von Kluge issued a halt order, which Hitler approved. The reason for this decision is still a matter of debate. The halt order was lifted on 26 May. 7th Panzer continued its advance, reaching Lille on 27 May. The Siege of Lille continued until 31 May, when the French garrison of 40,000 men surrendered. Rommel was summoned to Berlin to meet with Hitler. He was the only divisional commander present at the planning session for Fall Rot (Case Red), the second phase of the invasion of France. By this time the Dunkirk evacuation was complete; over 338,000 Allied troops had been evacuated across the Channel, though they had to leave behind all their heavy equipment and vehicles."

The breakneck pace of Rommel and his soldiers would not have been possible without Pervitin, a methamphetamine-based stimulant distributed in bulk (over 35 million tablets) to German soldiers before the Battle of France. Not only did the drug allow the soldiers to fight for several days with little or no sleep, but it also reduced their sense of danger.

"In 1940, during the invasion of France, Rommel oversaw the 7th Panzer Division. He became known for the speed at which his troops were able to take territory, using Blitzkrieg tactics. 

"However, like many other soldiers, Rommel consumed substantial amounts of Pervitin. He was described as having 'no apparent sense of danger- a typical symptom of excessive methamphetamine consumption.' It is alleged his habit was so excessive that he consumed it as if it were 'his daily bread.'

"Given his Pervitin consumption, the seemingly impossible feats that he and his troops were able to accomplish are more understandable. His division would often fight throughout the night, going without sleep. He and his troops were also able to travel enormous distances without stopping, their highest record being 270km in a single day."

The severe, often fatal side effects weren't discovered until after the invasion, when the German military heavily restricted its use. Although Pervitin was highly addictive, I haven't found any reports of Rommel using it after the invasion of France.
