Dysphoria, depression, derealization, anxiety and depersonalization are all common symptoms post GBL withdrawal. A diminished mental acuity can also be found in people with hardcore habits. All of these symptoms reverse and how fast depends on your willingness to excercise, eat well, and force yourself to engage in social interactions as to slowly force them to become rewarding again.
Hypertension/tachycardia or cardiac dysfunction is a very common symptom of GBL withdrawal because you've dealt a blow to your autonomic nervous system. This reverses in time like everything mentioned above.
