Hi, I started my 2 weeks on, 2 weeks off cycle for clenbuterol... I started 40mcg on e first week n 80mcg on e second, then I was off for 2 weeks. I felt alright with just a little bit of sides like trembling hands n slight headaches...

Then, on e second cycle, I started off with 80mcg n I felt terrible on e first day. Nausea, felt like vomitting and very bad headache... Any advice? Should I have just kept to 40mcg on e first week n 80mcg on e second?
