Not a doc, but I'm a nerd and am on Lamictal myself. Researched the s--t out of it. Up to 200mg now and have been on some dose of it since September of 2015. Very well tolerated.

1. I'm not sure about the anxiety, but it has been reported for sure than Lamictal can cause sleep problems. I wouldn't doubt it with anxiety though given everyone has unique brain chemistry.

2.As for hypomanic, I wouldn't doubt it. Titrating to 200mg induced ultradian cycling (within the day, in a few days) in me. So it could be.

3. The anxiety could be (if I'm correct in thinking that's what you're asking about regarding the withdrawal symptom) a side effect of anti-depressant withdrawal. Cold turkey or did you wean off? Sometimes even weaning can cause withdrawals, especially if done too fast. It is listed as a possible side effect.

4. If you have a rash of any kind, call your doc IMMEDIATELY. It may not be SJS, given it's super rare. And you really lessen the chance if you titrate up slowly. It's like .03% of patients that develop it, but with rashes on mood stabilizers like Lamictal, need to be careful. SJS is tricky. Try not to scare yourself though. Like I said, super rare. Again though, any rash. Call doc immediately or go to ER/Urgent care and tell them you're on Lamictal if weekend or can't get a hold of them. Need to make sure. If it would be SJS, you can't stop if once it's started. It's quick. Once it appears, it spreads fast. Fast fast. So you'd know, but again, if it's concerning, get it checked, and regardless of that, call doc ASAP.

5. For me personally, it was. It got me back on track. It evened me out, stabilized me. I got two As in university as a Junior of the four classes I took after not having had an A in a class since my Freshman year. It's FDA approved particularly for BPII but also for BP in general and is considered a "miracle drug" by many psychs.

Again, no doc, but a lot of med experience and person research done. Spend a lot of time asking docs questions, reading my med inserts, and I'm a clinical psych major. I hope I helped you some rather than freaking you out.
