I've been taking 50mg of winny for three days now and I am having trouble sleeping. The first night I hardly got any sleep so I went out and bought some sleeping pills. The second night I took two sleeping pills and slept a little better but not as well as usual. I can feel my heart pumping while I'm laying in bed and while I was at work today my heart felt like it was pumping faster than usual. Does anyone else have this problem? The first day I took the winny about two hours before bed and the second day i took it in the afternoon and I still couldn't sleep. I know rest is very important in growing and I'm afraid I'm hurting my gains. What can I do to get some sleep? Although it is still early I feel I have more energy in the gym and have been getting better work outs and pumps. Probably just mental but I have noticed a small difference. When should I start seeing results? I hear in week two, is that the beginning of week 3 or end of week 1? Thanks for your replies and I will continue to update on my winny only cycle.
