Just an FYI, my last batch of Pyridostigmine ended up being bad. Unfortunately, my prescription is a 3 month. I just felt so tired, more symptomatic than I had been in 40 years. Couldn't keep my head up for an hour. Refilled prescription, and suddenly I'm fine again. It's been over a month and the symptoms have mostly been mitigated.

It came from Zydus Pharmaceuticals. Prescription was obtained in May or June of this year.

Anyone else find something similar?
