Give it time. Your system has to adjust to the drug. You will be fine.
Regarding Vimpat... I've been on 200mg. for a few weeks now but recently had my blood thinners cut to half dosage. Since blood thinners were reduced, I'm now having more minor seizures... There is certainly a pattern somewhere. Before blood thinners were cut, I went 30 days with no seizures!
Did the same as you Lesley
works great for me
