I'm in the midst of a mega headache, so it's probably dampened my mood somewhat. It's hard going for sure, but I'm going for at least 98%. That's my goal. One thing I've noticed with this us that it goes through different phases. So one month you'll be going through a nausea phase. Then you'll get a head ache phase after the nausea has gone. Then my neck and back of head may play up. And round we go. Any idea why this occurs?
