is this a constant funk or an every now and then funk? it might be the hydros getting you down,they will turn on you after a while...or you might need anti depressants for a time,or it could be just you feel like crud since you had been sick....winter months are notorius for bringing on depression,i didnt check to see where you were from but this cold weather has been dragging me down!! it can be any number of things,but once you get off the hydros you will notice a difference in a very positive way...
your funk may be related to your hydro use. if you are cutting back on your pills you could be experiencing the depression od w/ds and if not it could just be from using....how many pills a day are you taking? for how long and how much have you tapered? those answers will help us know how to help you. dont give up..
