I tried it but I didn't really like it.
Now I'm on 5 - 7 x 70 normal mestinon. Dosage depends on how I feel and sometimes I take around 8 pm, 10.30 pm (in bed) and other days I take 6, 8, 10 pm so it's mostly the evenings that make the difference in how many times I take it

The timespan made me feel weird and jittery muscles.
