I was just about to suggest the same thing that Gr3tta did... sometimes I would feel this way for a bit after one of my drinking,smoking, bar hopping alters had been out.

I have also felt this way when my medications were not right...

suggestions contact your treatment providers they can tell you if you have drugs and alcohol in your system sometimes even 6 months after by testing your blood and a hair sample (which is how I found out what was going on with me)

your treatment providers can also make adjustments to your meds to see if its the meds that are causing this problem for you.
