A Bedworth dad who drank 14 cans of Pepsi Max a day and 'couldn't stop' has ditched his habit - after being hypnotized. Dean Gavin, 52, would have his first can when he woke up, and would even take a Pepsi Max to bed with him to sip on through the night. But the £3,000 a year 'heavy addiction' was wreaking havoc on his sleep and making his Tourettes tics worse. In a desperate bid to help him stop reaching for the sugar-free fizzy drink, Dean turned to a hynotherapist. The former farm worker – who was splashing out £60-a-week on 24 packs from Tesco - had switched from Coke to Pepsi Max after being diagnosed with diabetes four years ago. During three-and-a-half years he drank approximately 15,000 Pepsi Max cans – including 639,000mg of caffeine.

Dean, from Bedworth, said: “I have always loved fizzy pop and used to drink full fat Coke but I had to stop because I was diagnosed with diabetes. "I still wanted to have my fizzy pop fix so I switched to Pepsi Max because it was sugar free. I loved the taste and used to drink up to 14 cans a day.

I don't drink alcohol so when I went to the pub with friends I'd just have pints of Pepsi if it was on tap. "I’d even take a can to bed with me and drink it through the night when I woke up. I was so wired I could only sleep between two and three hours anyway. "I ended up buying big packs of Pepsi from Tesco and was spending around £60 a week on the stuff but I couldn't stop." Dean, who also suffers from rheumatoid arthritis and Tourettes, finally sought help with the help of his partner Donna. Dad-of-two Dean added: "Donna could recognise that I wasn't in a good place. I've got Tourettes and my tics were getting worse. "I felt edgy and wired a lot of the time and the lack of sleep wasn't helping so Donna did some research online and suggested hypnotherapy. The idea was a bit far fetched for me but I was willing to give it a try."

After just one two-hour hypnotherapy session and a follow-up meeting three weeks ago, Dean has not touched a drop of Pepsi Max since. Revealing what happened during the hypnotherapy session, Dean said: "David spoke really calmly to me throughout the session and when I left him I just didn't fancy having a Pepsi any more. Ever since then I've slept better and my tics have got less. I just drink water and juice now and feel so much better. "At first I had a couple of cans of Pepsi but nothing like the amount I was drinking before. I've saved so much money and I feel like I'm back in control." David, who specialises in treating people with eating and drinking obsessions, said: "I am so proud and honoured to have played a part in Deans recovery from his heavy addiction to Pepsi Max. Dean told me he struggled with anxiety if he didn’t drink it daily. "He even had to drink a can with his cup of tea in the morning, and even took one to bed with him. I wish him the very best in recovery and hope he inspires others to express caution in drinking fizzy drinks."
