had an accident because I slept while riding, alive from god's grace

tldr; i was coming back from a trip, slept on bike and fell on the other side. I'm fine but small hole on bike body. I started riding bike last year and got myself a VStrom 250SX start of this year. since then I've scanned through KA and TN, around 6500 kms. I feel sleep as soon as start riding all the time, even if i take a redbull or coffee, it lasts for 30 mins max. till now I managed to keep myself in check and took breaks whenever i feel sleepy. today I went for a ride and while coming back same thing happened. i was riding solo and thought nothing will happen and tried to push it and bam. right after that I fell asleep, went to the other side of the road and hit a pole. i was on 6th gear and around 80+ speed, that pole went complete flat. when I woke up i found myself trying to control the bike, man those 20 seconds, i'm still processing. I fell on the other side and somehow managed to pickup the bike, by god's grace nothing happened to me but there's a hole on the plastic cover on right side of the bike near engine. somehow there're no vehicles on the road at that time otherwise i wouldn't be here writing this. I'm getting chills now, feels like a second birth. I had a good sleep yesterday but not sure why it always happens ? is my bike or helmet too comfortable or is it some illness ? I need help getting some tips and if anyone else is having this issue please lmk. Edit: Thanks everyone. Feeling much better after going through all the replies and suggestions. Will try all of it out and become more responsible. Thanks again, I'll take nap now (no pun intended)
