bladder infection
"First day worked fine, although will say my pee was neon...wasnt expecting that. Second day however,  tired all of the time with a killer headache that doesnt seem to go away and very cold and achey. Good that I can finally sleep after three nights of not being able to (great bank holiday that was) and pain went after the first two tablets were taken. This is the second time ive been on these, would definitely take again."
