I went through the same thing! it takes a while to feel better., i felt like super duper shit after stoping opiates BUT you have to remember you have been pumping all those chemicals that make you feel good into yourself for a long time, your brain's ability to make those natural chemicals is compromised. If you were using alot then that state became "normal" for you...now the REAL "normal" feels like crap...you just have to get used to it. If u think you can take a few benzos here and there without abusing them i would say try that, it helped me..esp at night when i used to be using..and i know this sucks, but get outside and try to be active, excercise will release some endorphins that will help you feel better
AND Im almost sure two hydros wont put you into physical withdraw but mentally thats probably not a good idea...thats just me though, maybe u can handle it but if i did that i would just want more afterwards.
