5 Seconds of Summer kicked off their Rock Out With Your Socks Out Tour on May 4 in Lisbon, Portugal and have played shows in Spain, Italy, Switzerland, Denmark, Sweden and Norway too.

It seems like the hectic schedule of tour life is hitting guitarist and vocalist Michael Clifford currently on the road.

On Friday he tweeted, "don't feel too well today."

He made it known he was sniffling too.

Thursday after the show in Oslo, Norway, Clifford complained about the loudness he heard from his bandmates Calum Hood and Luke Hemmings watching a movie probably on their tour bus.

Luckily, they have off today and are just traveling to Berlin, Germany where they play a show tomorrow, May 16. They also have shows in two other German cities on Sunday and Monday, May 17 and 18. Hopefully he will be able to rest up and feel better. He should also probably stay clear of beer and settle for some tea. On Wednesday before the show in Sweden he had a beer, which perhaps contributed to him not feeling well in the long run since mixing alcohol, lack of sleep and possibly poor eating habits since that's typical of tour life can all affect your immunity.

Plus, constant traveling can also weaken your immune system and that's currently what the 5SOS band member is up to.
