Hello,
I've been taking 150mg of Velnafaxine for about six months now and have found it works for me. However, I was experiencing an issue that I put down to being on standard tablets. As these have a short half-life, it occurred to me that I was on a rollercoaster as regards serum level.
The issue was simple. I take my pills at noon and about 2am respectively, 75mg each time. By around 11pm, I tended to fall asleep, sitting up, leaning against my bed's headboard, or even just in a chair. The desire to sleep was undeniable and dropping off would be common.
This begged a question, is narcolepsy a withdrawal effect? This would fit with the drug's half-life expiring.
To counter this, my GP, as asked, has put me on 75mg XR per day. He'd like to see me taking less and I would too. SO far, halving the dose in this way has made no real difference at all.
any thoughts, experiences or suggestions will be welcome. Thanks.
David
