Ya, been on it for a while now and it is the only thing that has ever worked. I'm a mixed bag of labels and give them a minute and they'll change their minds again, but Bipolar and ADHD seem to be a strong ones, the rest, and there are many, all add up to Aspie, but they don't want to hear it, so I no longer beat my head against that wall with the Vet's Admin, or even here for that matter. Antidepressants and other mood stabilizers did nothing for it, zero, zip, nada. Then after about 10 - 12 years we lucked out with Lamotrigine. Be very careful with the dose, a little more then what I'm taking now was seriously dangerous and I'm not talking about a rash. Those weren't the fleeting suicide thoughts at all, but when you've lived it for so long, you can tell the difference. Get on the phone and get on it fast.
Often I have noticed, for myself, that the label dose isn't the same with me, a little seems to have more of an affect then what the labels and the Doc's think, so be strong and stand up for yourself and let them know. After all, they're only reading a label, you live it. They don't often add Ritalin with a bipolar mix, even to treat the ADHD, but it worked and if I still needed to work I would be on it still, but the blood pressure made me drop it till we figure some more things out. No two of us the same and what works for one won't for another, it can get very complex with the drug cocktails and take a long time to find the one that works or you can fall right into the right one/s. But oh so worth it, so very very worth it. Just remember, there will be no perfect, you will still have to weigh the pros with the cons. Good luck.
Oh and, this is the only drug that I have had a good level of a dose and they/we wanted to see if it could be adjusted to make it better, play with it in other words. In the past anything that even was remotely better, when changed with bad results and then brought back to the one that sorta kinda worked a little, it no longer did at all. This one works even if I change it and go back, it's a winner for me.
