I started with Lamotrigine which was magical, then nz stopped funding it and went to Lamictal. Regressed and felt suicidal. My neuropsychiatrist applied for a compensation and back on it. Taking 2x 100mg a day and an extra one anytime I feel a panic attack coming on. This has been up to 6x a day. Works within 15 mins which makes life manageable at the worst of times. good luck.
