Drouin leads the Bolts for goals since December 1 with 14, two more than leading goal scorer Nikita Kucherov.
Drouin said the couple of days away from the rink left him a bit tired at the end of the second session
Saturday, but he still has another day to return to normal before facing the Senators.
"I guess the first session's not that hard, it's just moving the puck and making plays on the power play," he said. "Definitely a long session today, and I guess it's nice to have a couple days to kind of get back into rhythm. When you're out a couple days, it shows in your skating."
When he's on the ice, Drouin has combined with rookie center Brayden Point to form a dynamic 1-2 punch for the Lightning attack. Drouin said Point plays a similar game to himself, which allows the two to have such great chemistry together.
"He's a smart player, fast," Drouin said. "He's going to be a great player in this league for a while. It's his first year and you can already see that. The way he plays, he demands the puck. He wants it. It's always nice to see when you have somebody on your line that wants it and wants to make plays.
"To have Pointer, the way he's been playing since he came back from injury, it's been great, and we definitely have a little bit of a connection on the ice."
RARE THREE-DAY BREAK: The Lightning have three days between Thursday's loss versus Calgary and Monday's contest against Atlantic Division rival Ottawa, an uncommon break this late in the regular season, especially considering the Bolts were on their bye week just a week ago.
The time off can be both beneficial and disadvantageous for the Lightning.
An extended break this late in the season is good rest for any team, especially with so many games on top of one another due to the condensed NHL schedule this season.
"Our schedule has been pretty packed, Drouin said. "You take the bye week and the all-star break, and it's been back-to-backs since. So to have those two, three days without any games, it's nice definitely coming at the end of the season like that."
Added defenseman Anton Stralman: "I think when you get into this last month and a half, I think you'll take any break you can get. I think it's positive."
Conversely, the Lightning are coming off a loss in which their energy level didn't match the effort of previous victories. The thinking then is the Bolts would like to get back out on the ice as soon as possible to erase that subpar performance from their memory.
