Hang in there, it does get better. For me, the first 4-5 days is the worst. Typically days 2-3 are my own personal hell. The hunger (physical and emotional) are insane. BUT, for me, the worst is the headache and ridiculous fatigue. (Well, and I always get diarrhea the first few days on Protein shakes). The headache and hunger fade over a few days. I swear after 4-5 days my body realizes I'm not giving up and the hunger starts to fade. Unfortunately the fatigue has always stayed until I'm allowed to eat more. My best advice is hide from the world, sleep when you can, drink Water or crystal light all day long and try to keep busy. Week 2 has always been a fair amount better for me.
It is SO worth it in the end....even the post-op liquid diet is a breeze compared to pre-op. keep your chin up and your eye on the prize!!!!! YOU CAN DO THIS!!!!!
