Hiya mate! I take methadone but unfortunately dont know what darvocet is (Im in England so possibly known by diff name here). What I would say is that meth is a strong opiate and so all drugs mixed with it must be done so with caution. Could you ask your pharmacist? Any 'downer' taking with meth is going to make you more 'relaxed/sleepy' so if thats what it is be careful of accidental overdose. Hope this helps in any way.......Im more than happy to talk thru it wiv ya a bit more if it would help.
