You should also not feel effects from your medication, in as little as 2 hours, since synthroid has a long 1/2 life and takes a while (days) reach full potential in your body, so the effects you feel today, would be from medication taken previously.
Since you react that quickly, I'd have to wonder if you are reacting to fillers/binders in the pills, rather than the medication.
You might ask your doctor if you could switch to Tirosint, which is a gelcap and aside from the active levothyroxine, it contains only water and glycerin, so is considered hypoallgergenic.
That was a very, very slight increase in dose. On the 88/75/75 pattern, you were averaging 79.3 mcg per day. On 88 six days a week and 44 the seventh, the average is not quite 81.7. A change of a mcg or two shouldn't have that kind of effect unless you were very, very close to being hyper at the time, and "results on the low normal side" wouldn't seem to support that. Anything else that might explain your symptoms? Change in brand name or generic to brand or vice versa? Other meds changes? Supplements? Diet? General health?
Are you ordinarily very sensitive to meds?
