Does anyone have success with low dose lamotrogine/lamictal (12.5-25mg)? Long term.

I'm very sensitive to medications and have tried 25mg lamotrogine before but I had systemic inflammation and my Dr pulled me off it after only 3 weeks...I loved those 3 weeks though and I'm thinking about trying to go back on it but staying at a very low dose..

Has someone else had success with low dose long term?
