Hi. I've been taking the generic form since April 2011. I sourced it online because I can't afford it otherwise. I took Genovir (from India) for 9 months to start with until that source dried up. I felt great on it for the first three weeks then got sick with headaches, fatigue, muscle and joint pain and so on but persevered because I'd been told that getting this kind of reaction early on was a predictor of a good outcome. After a week or two I picked up dramatically and continued to improve on it. Around the four or five month mark I had terrible stomach problems and was advised to go off it for a couple of weeks then restart, which I did. After that no problems and great gains again, with the odd few days of feeling unwell on it now and then, then bouncing back better than before each time. In Feb my source dried up and I had to go off it for 3 months. I was very worried about relapsing but in fact continued to heal and make gains during the abstinence period, and restarted two months ago, sourcing the Cipla Valcivir from the UK this time. Same as before, felt great for a month then got very sick for two weeks, dragging myself around and headaches, dizziness, justnwanting to lie down and sleep all the time. Just when I had decided that either I could no longer tolerate it or it was a bad batch, poor quality, i was being poisoned, or something like that and I would have to stop, I woke the next morning feelimg like a new woman and have been feeling absolutely wonderful since. It's been an godsend for me this drug. I've been sick nearly 30 years so didn't hold out much hope as the longer you've been ill the less likely it'll work but it has exceeded my wildest expectations really. I am totally pain free and have been for about six months. Pain (crippling fibromyalgic arthritic type) has been my constant companion for 25 years, only morphine could shift it. Its gone. I truly think I'm recovering for real. I wouldn't have believed it. You need to drink two liters of water a day on it and rest as much as you can.
