If you can, source some dopamine agonist. Meth is a dopamine and norepinephrine releaser, the pleasurable effects are a combination thereof but more problematic is dopamine. Lack of NE makes you sleepy and slightly depressed while lack of DA, depending on the individual, can induce a plethora of mental and even physical symptoms. Memantine, ropinirole etc. they help but at the other side will prolong the whole stuff. Memantine less so, as it's also a NMDA antagonist. Was the meth you were using pure, crystalline? I too get calming effects from stims and rage on rebound but 1+ grams is indeed a freaking lot, it was a month for me to take 1g meth and still got depressive withdrawal after a few weeks.
Alternatively benzodiazepines but I don't feel good recommending them as they can be very addictive themselves.
