"i took lithium twice by with no other drugs. first for a few days. i stopped because it made me feel flat &amp; it more difficult to think of the right word to use. my vocabulary &amp; ability to articulate were noticeably worse. i took it again at my doctor&#039;s advice- 300 mg for one week, then switched to 600 mg. the day i took the 600 mg i was so angry that i wouldn&#039;t leave the house because i thought i&#039;d pick a physical fight (something i&#039;ve never done). i stopped taking it altogether, and now my memory is much worse than it&#039;s ever been (memory has always been a severe problem for me to begin with). i generally have a harder time getting anything done, speak a lot more awkwardly now, and have been pretty upset that lithium made my life worse."
