I will probably have my prescription for Lithium written tonight. Are there things I should ask the p-doc about it?

So far I have thought of:

1. What maintenance do I have to do?

2. How can I minimize weight gain without messing up Lithium levels

3. How much water do I need to drink per day?

4. What about electrolyte drinks?

5. How long will it take to notice results?

6. What are symptoms of toxicity?
