ah, ((CN)), used to have those mania moments a lot. i thought, well i should lose weight cause i was so jacked up. you sound a lot like me....our sense of humor may save us in the end...of the knot. lol.
i take neurontin. what i discovered was when i was on higher doses like you are sometimes it would throw me into mania. i'm wondering if that could possibly be part of the situation with you. when i moved and got a new pdoc she recommended we lower the doseage. i kicked and screamed (in my head cause it has helped me soooo much with the BPD) but said ok let's try that. well it worked!!! now i take 900mg/day. now i'm not advocating you reduce yours without consulting with the pdoc but it might be something you want to bring up in a question.
don't take lamictal but most of these type meds take from 15-28 days to reach their theuraputic level in our body. i know lamictal has to be raised in increments when you first start, so best i can say is to hang in there...at the end of the knot! don't let go!!! my neice is BP too and lamictal is the bomb-diggity for her. she has responded well to it. so hopefully you will soon start to feel results from it.
feel free to pm me anytime...sounds like you have a very supportive family. that is especially appreciated when we are out of sorts, jme. my son is so understanding even tho he has no idea how racy i feel inside. he does see some of it on the outside when i go motor mouth a mile a minute...and he says, mom,mom, breathe, breathe, come up for air....it's so funny. hope you have a great day.
