"i&#039;m currently between diagnoses of bipolar ii and bpd. i started on 400mg lithium (taking my level to 0.3) and already felt some effects with it. i recently increased this to 600mg and whilst i feel like myself again, i have a few side effects. a lot of nausea, being put off of food, an extreme thirst (which isn&#039;t a bad thing because it&#039;s important to stay super hydrated on lithium!), minor muscle weakness and stomach issues. when starting and increasing the dose, i became incredibly gassy (thankfully, odourless!) and have had slight stomach upsets. i&#039;ve also found acid reflux to be a huge symptom for me also, whether it is caused by taking lithium alongside celexa (citalopram) and inderal (propranolol), i&#039;m unsure. overall, great drug."
