I'm Just Not Sure

I don't know if I'm liking this medication or not. I don't get the feeling of euphoria that my husband says he experiences. I don't know if I need a higher dosage or if he's exaggerating or I don't know what "euphoria" feels like enough to recognize it or what. All I know is, after I take it, I feel pretty good. Then, I have this overwhelming urge to take a nap. And, now I have a crampy stomach. I don't feel sick, just crampy. It says on the internet that this could be a side effect, so I'm not overly concerned. I just hope it goes away if I'm going to continue to take this stuff. I don't like pain, mental or physical!
