Hi all! I have a question, since iv been vegan iv had more energy but the last couple of days iv had little to no energy and one day two days ago I spent the whole day barely able to keep my eyes open. Iv been taking a B12 supplement and using my cpap and trying to be as active as possible. It’s also been in the 90s here so I don’t know if it’s heat exhaustion, a vitamin deficiency or what. I have been anemic in the past but not for a long time. Has anyone else experienced this? I wanted to maybe ask you guys and try to save a doctor visit.
