I just wanted to let everyone know that dehydration can cause severe depression. My boyfriend was depressed and was also dizzy. I took him to the ER and they ran tests on him and found that he was severely dehydrated due to exercise, eating too many salty foods, drinking coffee and soda, etc. His doctor said that the dehydration caused his depression, so they gave him 3 or 4 I.V. bags of water. After all that water, my boyfriend said he felt fantastic and his depression was gone!
I hope this info helps someone else because who would think something as simple as water could help depression!
