Gary Topley has been taking the oil – which is made from a compound of the cannabis plant – since February.
It was legalised in Britain last year and since then many people and experts have extolled the virtues of the oil.
Recovering alcoholic Gary, 39, said: “My life is changing and has changed so much because of this stuff and I want to shout about it from the rooftops.
“I sleep better and it has helped with my depression and anxiety – my outlook on things is much better.
“My general health and well-being have improved in massive amounts.
“I just feel now I can achieve anything.
“It has given me more focus and determination to the point I am now in a well-paid job
“I’ve got back into the gym and started training in Krav Maga and am more positive and motivated.”
Gary added: “It really is great stuff.
“It is non-addictive and perfectly safe and legal.
“To those wanting to take it, just give it a go and all being well it will help to improve your life like it has done mine.
“It has helped me so much I now sell it to try and help others.”

‘It’s a great choice if you’re finding it difficult to relax’
Dr Sarah Brewer, an award-winning writer and the author of 50 popular self-help books, also outlined the benefits of CBD oil.
She said: “CBD oil has a lifting and relaxing effect on mood with none of the adverse psychoactive effects associated with marijuana.
“It acts via the body’s own endocannabinoid system to promote feelings of wellbeing.
“It’s a great choice if youâ€™re finding it difficult to relax as it’s not habit-forming,” she added, noting that the oil is ‘particularly helpful for reducing anxiety, promoting relaxation and restful sleep’.
CBD oil went on sale at Holland & Barrett at the start of the year and the high street retailer boasted a 37 per cent increase in sales in the space of four weeks.
It is advised that people discuss CBD oil with their doctor before using it.
