A bit of a long shot but naught to loose. Does anyone have any experience/knowledge about taking lithium and specifically managing dehydration while out in the mountains. My doctor wants to prescribe it to me but having read through the potential side effects of toxicity I’m rather worried about the possible impact of becoming dehydrated during a climb. While none of treatment options have side effects I’m terribly happy with, the potential unpredictability of lithium seems to be adding quite a bit of additional risk to the situation.
