I'm bipolar 2, 95% of my problems are with depression. My problems started when I was prescribed AD's after DD2 and I went manic (I was 34, no MI before that point).
Just my experiences:
- Lithium (at a blood level of 0.5):
Physical side effects: made me sick 3-4 times a day, I had an unquenchable thirst and drank water compulsively (think 10 pints a day), I had a tremor in my left hand/arm that was so bad I couldn't pick things up, each evening after I took it, I would lose my sense of balance and stagger around.
Impact on mood: I was mentally very clear in terms of concentration, but I lost every hint of emotion. I felt nothing. My DD's would hurt themselves and I felt nothing. I kept walking out in front of cars and nearly getting run down as I didn't feel that 'oh crap, I better get out of the way' feeling.
Lamotrigine:
Physical side effects: none, so long as I don't go above 225mg. Above that, it affects my word-finding abilities (enough so that I can't work as I'm a lecturer.)
Mood: I worked the dose up very slowly from 25mg, increasing by 25mg every 6 weeks. Each increase would throw me into a terrible, agitated, suicidal depression for 6 days. After that, it would clear and my mood would improve. It took me a while before I realised that those crashes were related to the Lamotrigine increase. In the long-term, it's been a really good medication for me and really helps the lows.
However, Lamotrigine is not enough to keep the depression away. I also take Quetiapine (an antipsychotic) and Agomelatine (an antidepressant.) The real 'magic' is the Quetiapine, but I' definitely need all 3 to keep me reasonably well (although I still relapse at least once a year.)
