Finished 40 days ago. I feel horrible. Can I do it again?

Hi folks!
i finished 10 days of the Master-Cleanse about 40 days ago. I didnt follow some peoples' advice and i feel like i gained all the weight back (which wasnt my reason for fasting, but it was a good side effect) now i feel like i look awful. I feel awful. I tried the Master-Cleanse because of severe constipation. Nothing else worked. It returned right after I quit. Now i have this pot belly probably cuz i can't "go" and because i put weight back on. Has it been long enough for me to try again?
i can't work from home this time either. How do you all handle the constant trips to the lavatory when you're doing the Master-Cleanse and you're at work?
Thank you all!

oh! PS someone told me i can do the MC for just 1 or 2 days if i needed it. What do you all think?
