Still going strong at 99 days. I'm actually sleeping a full 8 hours without waking up (almost a week now). Feels like I'm coming down with a cold or something. Still having chest congestion in the morning occasionally and shortness of breath... but generally and overall much better. Glad I'm about to go into triple digits. Anyone still have "withdrawal" symptoms or anything after 90 days... wondering if the congestion and occasional shortness of breath are still my lungs healing. I walk every morning and it never really happens then. It's always later in the day after lunch...
