Discostu: I am no expert but I have been there. You have a great opportunity based on the info you have allowed. It still will not be a cake walk. I have taken hydro for 7-8 years. You will have diahrea, Imodium will help. Of course everyone's system is different.
You may have problems sleeping and may experience flu-like symptoms. You may get pale. I would drink plenty of fluids and vitamins. I would stay as active as your body would allow because that keeps your mind occupied.
Also over the counter tylenol pm or other sleep aids may help the first few days. The first few days will be the worst...I have faith you can do it.
Just to give you something as a guide...there have been many members that had been taking more than you and they beat the chain and that is awesome.
I am sure others will give you maybe even better advice. We are behind you no matter and it may be the biggest decision you ever make. I wish for your wellness and I believe in prayer, Think positive, many blessings, Risky Business,
