There is a chance that hydrocodone even at higher doses wont make you feel that great. People react differently to various opiates, sometimes you have to find the one that's right for you.
Give it another try at 20mg and see how you feel. Personally hydrocodone has never made me feel great. I recently took 75mg and just felt heavy, warm, and lethargic. Oxycodone however, even at much smaller doses, gives me very pleasent euphoria. Maybe hydrocodone isn't the right opiate for you.
Give codeine a try and see if that produces any euphoria, if not, maybe you need something like oxycodone.
Keep in mind however, 10mg even with no tollerence may not be enough to produce any pleasurable effects. My first time with opiates was also hydrocodone. It took 30mg just to get that warm relaxing feeling. I'm not saying go for 30 or 40mg right away, just work up too it. Also you will have to use CWE if you go higher then 20mg at once.
