Tenant issues due to alcohol

[Dan Dahlke]

I have a tenant under lease until next April. He was a recovering alchoholic, currently back drinking. Would get drunk and text during the night sometimes to 3am. Said we weren't going to allow it, so now he emails when drinking 5-10 times a day. I dont want to deal with this (self-manage) for another 8 months of his lease. Do I have a legal way to evcit based on harassing messages? Or what are my options.
