Does anyone have experience with bipolar disorder?

About two years ago, I was diagnosed with bipolar disorder.
Now that I have insurance, I am seeing a psychiatrist again. I am tapered up to an effective lamictal dose and I’m experiencing some strange feelings. When I was off the meds, I felt emotionally “flat.” I didn’t feel much of anything other than high energy or low energy. Now, I actually feel calm and content when I am stable, but I’ve been getting this anxiety on my downswings that feels like I got kicked in the stomach. I get dizzy and get tunnel vision and feel like I’m going to vomit.

I’m starting to see this as my way of adjusting to having a full emotional “palette” again. I’m experiencing emotions I haven’t felt in years and I don’t know what to do with them so my body reacts physically.

I’m just wondering if anyone has been through a similar situation with psych medication or knows someone who has and can lend some validity to my self-analysis. I’d like to hear others’ experiences in order to better understand my own.
