Not to promote drug use whatsoever (ironic statement lol), but I am on 1.5 grams of gear now and to combat the anxiety (especially at night time, when it really kicks in) one half of a 5 mg diazepam (valium- lowest dose available) does an AMAZING job at chilling me out.
However, I obviously am against doing anything stronger than that... Anything narcotic or pain killer can only make the anxiety worse and those things don't mix well with high dose gear.. Turns regular, good minded guys into bad people.
