Hi there ~
I understand your concerns. Tiredness
, extreme dryness in eyes even on using drops, excessive hunger with smoking meth
are common symptoms and your suspicion about your adult daughter do not seem to be unfounded. I believe you have cause for concern as she also has narcolepsy
and is staying with her grandfather at hospice which is even more stressful. I also believe that you might not be able to get her to go to treatment very soon but will be able to get her treatment involuntarily if you have evidence for her usage and can have her committed to treatment with a court order. I hope you do so as soon as possible for her own sake and get her on the path to recovery.
I hope this helps. Take care and have a lovely day!
