I went back after 9 days. I used the timer on my phone to remind me to drink every 15 minutes. I felt good the whole time. Now I'm just starting week 4 and just started to have some mild nausea and dizziness. We are doing a blood panel to ensure I have enough nutrients. My doctor gave me the go-ahead for pureed food and told me I could add fruit to my protein shake. But we are realizing that bananas might have too much sugar, causing me not to feel so hot. So today he told me no more bananas. It's day by day. I have learned most on this site that we are all very different. I choose to talk with my doctor about my specific issues and then work it out from there. Lots of days off are nice if you can afford it or if you have a job that allows for that but I am new at my job and still trying to prove myself. Again, we are all in different situations.
