I too suffer from intense irritability at times so you have my deepest sympathies. Meds and distraction are what works for me. Either on its own is not enough. At the moment I am on a amssive dose of Olanzapine and Diazepam to stabilise me (10mg of each, 2-3 times a day) and hopefully i can start reducing that soon as my symptoms are stabilising. Are you seeing your pdoc soon. It would be great to talk to him/her about this and perhaps tweek your meds and find some more coping strategies.
