Hi, this is day 4 for me. haven't been able to sleep since i started. very intermittant sleep and wake up beyond exhausted. i'm thinking of starting coffee and haven't done that for 4 yrs! NO Ketosis in sight still. less than no energy and cant even go on my walks or do my workouts. i dont know if this lcarb is for me. cant work...cant even function. and am still sooooo hungry and ate 2400 cals yesterday! more than i ever eat. my normal intake is probably around 15-1600. my legs and arms feel like they will give out. my appetite does not go away, it just gets worse! should i start drinking coffee? nothing satiates me. it's ridiculous!! is this just carb craving? and have gained 1 pound. how much longer should i do this before giving up? sorry about this post being so "desperate " but that is how i feel....
