Focalin help Problems?

[over1999]

Here is SWIM background;
Diagnosed with adhd years back and took ritalin 2 or 3 times a day.
Then SWIM was switched to Concerta (not sure it worked very well), then Ritalin LA.
The Ritalin LA was making SWIM kind of anxious.
SWIM did try addreall for about 2 months, felt great but could not eat well on it.

Doc then gave SWIM Focalin. It is supposed to be safer ???
SWIM has used it for about 3 years now. SWIM thinks it was working well until recently. SWIM takes 10mg in the morning, and 10mg around 2pm.

SWIM feels extra stressed out. Anxiety over everything, and down (for no reason). SWIM finds themself arguing with girl friend and parents more.
Example: If SWIM can't find checkbook or stuck in rush hour traffic, SWIM gets super aggitated. SWIM might beat on the stearing wheel.
SWIM diet did not change, blood work ok, life otherwise is ok, but something is wrong. The doctor has not given SWIM any real answers, but gave some Tenex for anxiety, stress. It helps SWIM a little, but it still doesn't seem right.

Anyone have any info to help SWIM?
SWIM is not having any fun
