Thanks for writing in to us.Methamphetamine
(meth) can cause slow, shallow and labored breathing
. This is what you are experiencing as unable to take a deep enough breath and not getting the full yawn.
With increasing use of the drug, there are strong indications that users suffer brain damage
, including memory impairment and an increasing inability to grasp abstract thoughts. Those who do manage to recover from addiction and retain memory and the ability to function in society are usually subject to some memory gaps and extreme mood swings.
Other signs of meth abuse are as follows:
Stopped breathing (sometimes fatal within 2-4 hours)
Bluish fingernails and lips
Spasms of the stomach and/or intestinal tract
Low blood pressure
I urge you to take professional help and check in for rehab services.
Hope this helps
