Hi there, I m very worried that my boyfriend might be abusing cocaine. He told me he s used it in the past .. unfortunately he does not live in my area so I can t be there to monitor or even be there for him. He s gotten very quite the past 2 weeks and I am so worried. He experiences the shakes when he get s hungry and sometimes it will be only a few hours since his last meal. He has quite serious anxiety, issues falling asleep (sometimes) but will more experience interrupted sleeps (waking up randomly). Lately he s been super tired. He will also tell me that he is generating more saliva than normal. I don t know if that has anything to do with it or if all these things are related to something else, but I would really like some expert feedback with this. Thank you so much!
