Horrible Thoughts

Just lately I've been getting moments where I suddenly feel the urge to break something - whatever I'm looking at basically.  I don't think I'm particularly worried, I'm just getting fed up of it.  It's happing several times a day and I'm wondering whether it may be due to the medication increase a couple of weeks ago.  I looked at the leaflet that comes with the medication I take, wondering whether it could be due to the recent increase in dosage.  "Aggression and irritability" is listed as one so it could come under that I suppose.  It would be a shame to reduce it again as it is controlling the seizures pretty well now.
