Can anyone tell me what is wrong with him? Today he woke up looking like he hadn't slept for a week. Extremely tired. And then he kept forgetting to eat. When we went out I asked him to get food for our son and he went and then couldn't remember where he left us. He then went for food twice and came back without anything. He is slurring his words. He hasn't really eaten anything today and can't seem to remember anything in the short term at all. He didn't go out last night. Is it drugs related? I don't know as I've never done them. He did them a long time ago but hasn't since before he met me so at least 10 years.
