For Sure, I take adderall and I get mad anxiety for no reason, sometimes it just hits me like a brick and sinks into my stomach dragging me down into a terrible feeling. It used to be so bad that I would smoke weed all the time cuz that was all that would help. It also made me quit my meds lots of times always with bad results.
Nowadays I get xanax, but I really don't want to take a xanax everytime I feel that way. Now, I just take a deep breth, and for a moment try to step out side myself. What I do Is I try to think nothing. Its not easy, we all have a little voice that is always saying something; some thought always running through our minds. With practice, you can make it be quite. Think about nothing but your breathing. Focus on it and imagine positive energy coming in with every inhale, and negative energy leaving with every exhale. Usually, if I can breathe out those first few stabbing pangs of that inexplicable feeling, then for the rest of the day I'll be OK. Just tell yourself you'll be OK, bury yourself in your work, and you will be OK.
I am coming off of Focalin after a week because it causes me very high anxiety. Can't stand it at all.
I haven't experienced stress or anxiety due to my adhd meds.
