My fianc has been on ambilify for 3-4weeks. he does not sleep, always irritated, taken on smoking, talks excessively, suicidal, claims nothing wrong.

Hard to care for: Your position is a hard one. Caring for someone who is resisting is very difficult and may not have a good answer. Surely no one thinks being suicidal is just fine - but he may not mind the other parts. You might benefit from some sort of support to keep you from going down w/ his ship. If you can find a therapist to trust you may be able to let him know you care but need to protect yourself. Sad
