Well the timing has clearly gone wonky somewhere, but I just (2347) got awarded 500XP for my first catch of the day - which very much was NOT the first catch of Sunday, but maybe the servers are confused & think it's already Monday?!
I finally managed to evolve my Wheezing (still sounds so wrong..) on Friday morning by walking my Koffing buddy. Walked Eggsecute from then & have just got a candy - I've only been out to GP to collect prescription & to Brownies & latter did not permit Pokémon-ing as got lifts to & from. Have played on & off over weekend, but my avatar doesn't walk much at home. The spawn spot over the road has started to produce things other than the interminable procession of rattata, pidgey & spearow - still plenty of them (well, this is Inner London, it'd be wrong & unrealistic not to have rats & pigeons all over everywhere...) but other things breaking up the monotony now.
Am hoping that I'll be well enough to go to ballet, um, later (it seems to be past bedtime, I blame the cats...) & then go on a Pokémon Hunt up in town. And my hospital appointment at Guy's on Thursday is bound to be so late I have to miss ballet (because that clinic is ALWAYS hours behind...) so I plan to head over to the IWM after that because I need about a billion bulbasaurs...
Really annoying that Guy's is nowhere near as good as Tommy's for Pokémon when am guaranteed to be trapped there for so long. Grump. Although it was a tiny bit embarrassing last week when I was catching a Pokémon when called into my appointment in the pain clinic & as I went to put my phone on silent, inwardly lamenting the waste, had to explain to the nurse specialist who manages my care & the opiate clinic lead (who I was meeting for the first time) that no I very much was not taking a photo of the consulting room I was trying to catch a tiny monster with my phone & they had interrupted me 
Have swapped to buddy a Grimer as need 10 more candy to evolve & I've not seen any info on hotspots, whilst I might be able to get myself to somewhere eggsecutes are known to be. With both of them it's been a case of one caught & one hatched - the Grimer I caught the first time I went through the "new" London Bridge to the underground (even that could not make me kindly disposed towards the new set-up); the Eggsecute was on a train - having been inspired by this thread to look up maps I now know there is/was a nest near the Millwall stadium: I must have been VERY lucky timing-wise!
