i go to the toliet alot and feel tired all the time,i feel shakey n have no energy . i also crave fizzy drinks alot and have no sex drive.

u mean u dont v moni yet drinks?
i dont understand o

when did this start with you?

okay two things:

1) stop craving fizzy drinks so that you don't add diabetes to the mix

2) go and see your doctor asap

PS: please why do ppl come to nairaland instead of going to see their doctor?

Cravings for sugary drinks is not something the OP would be able to stop by choice. Coupled with excessive toiletting and general body tiredness, he should be suspecting parasitic infections
Most parasites rely on sugar for their survival and reproduction, they use up your own store of energy making you tired and forcing u to consume sugary foods to replace the lost energy. In turn as soon as u do so they use up the energy again and vicious cycle continues.
Eg Candida, blood flukes, various intestinal worms

@ op I dont think your problem is that of worms or parasites. you need a proper medical check up see your Dr ASAP
