Also having the same feelngs. I started in January, got up to the 1 mg dose and the stomach pain and "gas" was unbearable. My Dr said I could use 1/2 the dosage, and I feel this is not strong enough. I am back to smoking, as of 2 weeks ago,want to try again, but do I have to go back to square 1? I had the vivid dreams, moodiness and about a 25 lb weight gain even though I am biking, walking and swimming 4-5 days a week. Any advice?
