My suggestion is that, don't make any bitcoin transactions if you're drunk, not in the mood or feeling sleepy because you might skip checking it and you might put a wrong address. Also ask the receiver if the address is correct, any mistake can lead to a big cost of losing your money.
Using shorter addresses are much effective in sending and obtaining money from the wallet. It is very important because it helps you to prevent losses and be comfortable with your accounts. Easy to remember wallet address is more noticeable and very quite safe.
Always double check first the wallet address that you're going to send to.
You sent wrongfully, at least it was not much to hurt you so much financially, imagine you was trying to buy a house that cost 300,000USD and you just lost it in one go, it is not that you are not careful, this things happen and they happn to even the best of the best too, your computer is secure, anti virus updated, no penetration but yet it can still happen, people go to long length to make this happen, so its better safe than sorry.
